How to set boundary conditions on arbitrary nodes in complex geometry

[syusaku625]

Why are the boundary conditions such as non-slip and inflow conditions not included in the loss in the example (aneurysm3D). I tried doing 3-D test calculation and cannot get a solution (loss doesn't decrease enough), probably because it does not consider the loss of the boundary conditions.

And I couldn't understand why epoch is set only 1 step in aneurysm3D example. Is it enough to predict three dimensional flow field ?

Thank you for informing us about your concern. We are currently working on incorporating a wider range of boundary conditions in our package. However, if you would like to help us out, you are more than welcome to contribute to the package.

Regarding the number of steps, as you mentioned, it may not be sufficient.
