I have created a new from from a deformed mesh using mesh view. I want to use the existing stress stress field for the deformed mesh. So I created a tensor functional space using a submesh and Tried to project the stress field onto the subspace. But I get error stating that the point are outside the…

Following is a minimal example that reproduces your error message. Here I have removed all code not relevant for reproducing the error. For instance, I have removed your solver, and simply added an expression into the appropriate space. import numpy as np import dolfin as df E = df.Constant(110000.…

Please consider the following link, particularly regarding construction of a MWE: [image] Read before posting: How do I get my question answered? Here are a few tips to help get your question answered: Phrase the title of your post as a question and make it meaningful.…

You need to have a complete code, this means that we can copy-paste the code in to an editor and run it, without modifications. Currently we are missing several key definitions to be able to reproduce the problem. As @nate stated, please follow the guidelines.

I don’t know if I can post the entire code online, As it uses a lot of functions

You should try to reduce your problem to the smallest possible problem, with as few variables as possible, that reproduces your error. See for instance: How to define a Function in a submesh based on function values present in an adjoining submesh? - #4 by dokken which reduces the original example: H…

Please format your code using ``` such that the code is properly formatted (and has the correct indentation).

First of all, why do you have both SubMesh and MeshView in the same code? You should only use MeshView.

even if I remove It won’t change anything.

The error comes only if I deform the mesh in line 97-100.

As I have said in the previous posts, please remove all code that is not needed to reproduce the error message. It makes it alot easier for others to help you if only the relevant code is shown.
