Different PDEs for different points

[bakhtiyar-k]

Hello,

If I have two sets of collocation points (red and blue), how can I specify two different sets of PDEs for them and run the network training?

I think domain decomposition is not supported by DeepXDE. You can try NVIDIA Modulus as they have a comprehensive library to handle such cases.

You can use if/where condition to specific the location in your PDE definition.

tf.where(condition, pde_set_1, pde_set_2)?

Yes.
