@praksharma Thank you very much for your advice. But after my attempt, it seems that it can not solve my problem very well. I can't build a cylinder in geometry,...

@praksharma Thank you for your reply. I can understand the first half of your proposal. But I don't quite understand what you mean when you say that extract boundary coordinates...

@praksharma Thank you for your patient explanation. Now I think I understand what you mean. You are saying that all BCS and ICS need to be converted to PointSetBC for...

@praksharma Thanks for your advice, now my 3D model works as well. However, the results are still somewhat lacking, and I would like to ask some more questions. It's about...

I tried your suggestion, but the loss of BC is still large.

@lululxvi Dear Prof. Lu, Now I have a similar problem. I want to expand the calculation in two dimensions of a square, but my boundary conditions only need to set...

@lululxvi @forxltk Thank you very much for your advice. I updated my code based on your recommendation. That worked for me. Now I have encountered a new problem, I hope...

@forxltk Thank you for your timely reply. I tried to set the following loss weights in the model, and the results improved a lot. `model.compile("adam",lr=1e-4,loss_weights=[100,100,1,1,1,1,1])` For the loss weights, I...

Hello @lululxvi , In the process of modeling, I found that the prediction results of the model only meet the boundary conditions when the time is small, but do not...

@lululxvi Thanks for your help! I'm having problems constructing complex geometric areas. I want to build a rectangle area with a circle subtracted from the inside using the following code....
