I have been working to create a simulation with a moving mesh that moves quite a large distance. Currently this is the break down of my simulation

Simulation begins
Interruption control when min orthogonal angle reached
Remesh configuration
- User defined
- Its kinda funny how it works but long story short, when remesh kicks in, it opens my workbench project that contains the geometry and mesh. I change a parameter defining the translation so far update the files save it and close. When work bench closes it reads the new mesh file (created by workbench) interpolates values and continues the simulation.

This may repeat as many times as needed until the simulation has finished.

What i would like to do is only remesh part of the full domain. As it stands there is an inner and an outer domain. The inner domain's mesh does not deform so to reduce computational time and errors due to interpolation, i would like to only remesh the outer domain.
There is a setting in the remesh configuration for "Location" however even when i only specify the outer domain the full mesh is replaced. Does anyone know how to fix this.

If your confused by my issue or have any questions regarding set up please just ask

Thank You,

DM

I can't export Geometrical Parameters (that i want to modify my original geometry) to new workbench for regenerate mesh or REMESH.
Please help me and if you can, Email a sample Remesh project to my Yahoo mail.

Hi Doginal,

I'm working on the AMP remeshing approach too n i would say the biggest snag is the interpolation error. I've not had any success with reducing it significantly, except by isolating it by reducing the timestep so that the results recover within a smaller simulation time window or blowing up the coefficient loop no., both which are extremely expensive workarounds for the problem.

You can reduce the meshing time by sub-dividing any curved surfaces on your body. But for complex geometries or when working with fine mesh of 2million elements above, the time for interpolation error to recover is anywhere from 10 to 100 times longer. Thus I wouldn't worry about the remeshing time.
