Mesh modification

Please login with a confirmed email address before reporting spam

Hi all,

I'm trying to find the displacement in a fluid solid structure where the fluid flows inside a channel and displaces the solid. The length of the channel is 10 mm, made of PDMS and Young's modulus of 2.2e6.

When I run the model, and extract data, it only gives me the displacement very close to the end of the channel (9.8-10mm ) instead of the whole length of the channel (0-10mm).

What are the possible solutions to get the displacement for full length of the channel? I tried to modify the mesh, both defult options such as fine, finer, etc., and changes the mesh manually. I could improve it only 1%, but this is not sufficient.

Appreciate your help and time! Thanks in advance.
