Hi, I am trying to interpolate a scalar field between two different meshes in parallel using transfer function. However, it returns an error. I attached the code here: test.edp (3.5 KB) The first transfer trial would return an error, Exec error : exec assert. Do you know what is going on here? …

Hi prj, Thank you for your answer. I have considered that this may be caused by the position of buildDmesh(), however if I called buildDmesh before defining fespace ( test.edp (3.4 KB)), the program got stuck after printing “here”. The code would occupy more than 256G of memory and remain unfinished…

It’s impossible to debug further without the meshes.

Hi prj, The size of the mesh file exceeds the limit of the forum. Do you mind if I send you via email?

Can’t you reproduce the issue on smaller meshes? If not, please use a file transfer system like https://wetransfer.com or similar.

Hi prj, Thank you again for helping me. Here is the link to the files for reproducing the problem I met: WeTransfer - Send Large Files & Share Photos Online - Up to 2GB Free . It includes two meshes for interpolation and a data file to be read by code and interpolated between meshes.

Can you reproduce the issue on a smaller mesh?

If you don’t mind me asking, what are you trying to do? Put each platelet on a mesh vertex or something? Unless you already have done so, you may want to start with a smaller system just to get some idea of the issues you will encounter and quickly get initial feedback on the approach or model. …

Your code is not consistent. kcoe appears to be a local function, yet you read inside sol_files/kcoe.sol which appears to be a global function. Please make your code consistent.
