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 disaster...as 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!

why don't you try with diffusion option.
