Hi guys!!!

I attached a picture of the result of a simulation using the dynamic mesh.

You could see a square on the right (the dynamic mesh zone) in a flow domain that moves according to an udf.

I used the Spring-Based Smoothing e Local Remeshing Methods to update the mesh but the result was a you can see.

I set the following parameters.

For Spring-Based Smoothing Methods :
spring constant factor = 0
boundary node relaxation = 0
convergence tolerance = 0.001
number of iterations = 25

For Local Cell Remeshing methods I used the values of mesh scale info.

Could anyone suggest me any way to fix the problem with updating of mesh?

Thanks in advance!
