Chang Haonan cleared his throat:

"About next month, the first trial version of the software will be officially released, and as long as you submit a trial application through the official channel, you can get the qualification for the beta version."

"During the public beta phase, the software is completely free, but when the official version is released, there will be an annual license fee based on different user levels and versions."

This kind of play has been proven effective by countless Internet companies in the future.

Start with low or free to build user habits, and wait until you have enough market share before you start charging.

Although Chang Haonan did not develop software to cut leeks and make quick money, the principle is similar after all.

"Then this official channel ......"

The routines that people in this era have seen are still relatively simple, and Rui Xiaoting was naturally attracted.

He even ignored the "licensing fee" section that followed.

Besides, he didn't pay for the money himself anyway.

"When you go back, I can give you an activation code, and when the trial version comes out, I will send you a box of discs by mail, as long as you enter the activation code, you can use it."

"As for the latter authorization, as long as each agency pays a fee, then the entire organization can use it, just like the current commonly used AutoCAD."

The main user of commercial software is not an individual, and the authorization threshold is not the act of acquiring the software itself, but the commercial behavior of the user using the software, so there is basically no need to consider any piracy issues.

In other words, for example, Jinling University of Science and Technology bought a license from Chang Haonan, so research and commercial activities with it as the main body can legally use this software.

As for whether the software installed in each person's computer is genuine or pirated.

Unimportant.

And having said that, it's only 1997, and it will take another two years for Juhard to let pirated Windows and office circulate all over the world in order to occupy the market, and the domestic software copyright situation is much better than at the beginning of the 21st century.

"In addition, I know that there are many universities and research institutes in Jinling, and if you can recommend our software to other brother units, you can also get corresponding discounts when you get the license in the future."

In fact, because Chang Haonan is still leading a project team, the nature of which is still a scientific research institution, so there is no specific sales principle.

However, this did not delay him from continuing to refer to the promotion model of Internet products in his impression.

Rui Xiaoting looked at Chang Haonan next to him with a sincere face, and always felt that something was wrong.

But after thinking about it, I always feel that I will not suffer any loss:

"Okay, then I'll try it first."

Soon, under the guidance of Chang Haonan, a new model was imported into the computer.

"It looks completely different from Guardian 1......"

Chang Haonan looked at the 6 rectangular directional tubes on an 8*8 chassis launch vehicle in front of him and said.

Even a pure layman can see the huge difference between the two.

"And why do you look more like a missile......"

"After all, technology has advanced."

Rui Xiaoting said as he made the final fine-tuning of the model:

"The previous chassis was selected in 92, whether it is carrying capacity, off-road performance or stability is not very satisfactory, it just so happens that now Wanshan Special Vehicle is cooperating with the Minsk Automobile Plant, planning to start producing a localized transport-erection-launch vehicle chassis next year, we will temporarily use the parameters of MAZ543 to build a mold, and then fine-tune later."

Although the elastic support theory no longer requires the hull to maintain absolute rigidity during launch, the vibration amplitude and period should not be exaggerated for the sake of fire density and hull life.

"As for the directional tube...... In fact, this can already be counted as a launch box, two launch boxes are a group, each car is equipped with three groups, so that after the fight can be reloaded, put the new launch box prepared in advance to continue to play the second round, according to our calculations, this can shorten the fire interval between the two rounds of launch from about 30 minutes to less than 10 minutes, but this function must be purchased at the same time our specially designed reloading crane to achieve. ”

Chang Haonan suddenly felt that there was some chess opponent.

When it comes to bundling, you still know a lot......

Then he went on to add:

"Of course, if the customer is really shy in the pocket, then they can also choose to use the original Iron Horse XC2200 chassis and the same directional tube as the Guardian 1."

An 8*8 TEL chassis is a rather expensive thing.

For most equipment using this type of chassis, the cost of that vehicle will typically be half or more of the overall system price.

And except for a few countries such as Da Mao or Huaxia, it is true that not all users have a particularly persistent pursuit of cross-country ability for long-range support firepower.

While the two were chatting, Rui Xiaoting had already completed the debugging and inspection of the model quickly.

"Uh, what am I going to do after that, do I have to copy the model, or do I have to redraw it?"

As he said it, his eyes flashed to the graduate student behind him.

Bringing an extra person over isn't just to carry a bag.

The latter only felt a chill spread from the soles of his feet.

Draw a picture of this level of complexity on the spot......

"No, you just add a statement that calls the program file in front of you, and we have reserved an interface to all common modeling software engineering files on the market, including SolidWorks, which can directly import data."

Chang Haonan didn't know that his image was close to the savior in the heart of someone next to him.

"So convenient?"

Rui Xiaoting quickly typed a sentence as she said.

Sure enough, a prompt appeared on the screen that the data was successfully called.

After a few seconds, a new dialog box pops up with a modeling diagram of the new rocket launcher.

“……”

In this era where even hardware versatility is poor, almost no one thinks about the versatility of different software -

There are no technical barriers, but in order to seize the market exclusively, some software developers deliberately differentiate their file formats from their competitors.

It's hell for engineering.

Even if the underlying parametric logic is exactly the same, it takes a rather complex transcription process to call a blueprint from one software to another.

Even a very skilled person can take several hours to complete.

If you're a little unlucky, you might even have to redraw.

Now, he did it all in less than 5 minutes.

"Next should be the meshing ......"

As the progress continues to advance, Rui Xiaoting's operation has become more and more proficient.

"Uh...... Why are there so many options here? ”

In a command line interface that pops up on the screen, 5 options appear.

The point is that he can't read any of them.

"Oh, here's our preset 5 different meshing algorithms."

Chang Haonan explained:

"Your model is a bit big, and one generation may explode the memory, so you disassemble the directional tube, bogie and chassis into three parts and generate them separately, and then choose the second one."

"Can you split it into three parts?"

Rui Xiaoting's hands on the keyboard shook, leaving a few irregular characters on the screen.

You must know that when he did finite element analysis before, this step even had to generate subdivisions such as hydraulic outriggers, girders, and auxiliary frames separately.

"If you find it troublesome, you may ...... It is also possible to combine the bogie and the directional tube. ”

Chang Haonan said in an uncertain tone.

"No, that's not what I meant......"

Rui Xiaoting's whole body was numb.

It is easy to go from thrift to luxury, and it is difficult to go from luxury to thrift.

Even if the software in front of you doesn't even have a serious graphical interface, the operation needs to be carried out from the command line.

But thinking about the fact that after going back this time, I still have to continue to accept the devastation of ABAQUS, and I feel that the world is gray.

So he made up his mind that when he returned to school, he would ask the principal to take down the authorization of this thing at all costs.

What money is not money.

Vulgar!
