Hello StarLabz, Hello all,

when I started to write the program, my idea was to create a product which would be able to simulate easily many clothes.

As things progressed, I found so many differences in the cloth meshes that I had to add parameters to be able to manage the simulations. These parameters are necessary to resolve all the situations. I certainly will add other parameters in the future but I never will delete one of them. If a parameter is in the interface, it is because it is useful.

I come from the simulation field and professional simulation programs like Abaqus certainly have tens of thousands parameters. These programs have these parameters because they are useful. One cannot say these programs are bad because they have a lot of parameters or they are difficult to use. I don't want to compare VWD to Abaqus but in both case, we try to do the best simulation results. Modestly for me.

ZBrush is a marvelous program and I will not compare VWD to it. I and now, with Dan, we work on the program, its documentation and its tutorials slowly. My incomes for this year with VWD, before the start of the V2, are less than 2 days of my other activity. "Time is money", perhaps, even though I am not, as Dan, so sure of the truth of this sentence. "Passion is time but not money", this corresponds better to VWD currently for I and Dan.

To come back to the simulation, a lot of ingeneers tried and try again to simplify the simulation programs. The result is not good. Not because they are not competent, but because a complicated field has to be transformed in complex field. The first one has almost no solution, the second one has a solution based on a decomposition in simple actions. The program which will allow to work on a complex domain will be complex itself, but not complicated.

I fully agree with you, we have to explain VWD using tutorials. Sorry if my tutorials have been made with a bad English, I can do them in French (I would like to do so) but I don't think they will be useful to you. I want to do many tutorials in (Bad) English because Dan does not understand perfectly French. If these tutorials are understandable, they will be uploaded as is, otherwise, Dan will help me to redo them with a perfect English or will redo them himself.

I consider this new V2 version as the start of a new life for VWD. We know we have a lot of improvements to do with the program. Every days, I do simulations, I had some issues I tried to correct, but many simulations work fine. I think my first work will be to explain the good rules in the use of the program. This will help everyone to reduce the error messages even though I will have to correct them in the program later.

Please, understand that this message is not against someone or something, it is just here to say that I am happy to work on VWD. I will be happy to continue to do this work with the help of the users and Dan. It is necessary to know that I asked to Dan to accelerate the generation of this version because that was, for me, its last chance. Too much time, not enough money. At one point, this ratio is no longer acceptable. I thank him a lot for that.

Have a great day.

   Gérald
