SPINN只支持[x y z]的输入设定,内置的Helmholtz也只支持3d #1074
Comments
你好,在 #1075 中已经进行了修改 |
原论文似乎没有考虑对于时间的处理,所以你知道时间变量该如何处理吗? |
我看原文以及源代码里并没有单独考虑时间变量,是和空间变量一样,也是一个branch SPINN_4d-L184 |
另外不是很理解 另外SPINN文章里说不同维度的branch没有必要采样数一样,PaddleScience里对不同维度采样数量N不一样时报错? |
|
目前PaddleScience的对于sympy.diff的处理是映射到paddle.grad这个反向微分接口上,暂未支持前向微分。至于时间t的输入,我晚点会参考SPINN代码加一下。感谢反馈问题 |
