mov Section

Purpose:

The mov section of the expert grid generator file controls the mesh movement process. These parameters allow the user to control the amount of the mesh that moves rigidly with respect to the adjacent surfaces. The surface motion can be controlled independently via the mvs egg.

Example:

mov 1
0.5
7.0

Number of Lines:

1 or 2 lines

Description:

Line 1: Mesh Movement Rigid Control Parameter

This parameter sets distance within which elements move rigidly with respect to the body. It is a factor that is multiplied by the maximum boundary movement. The default is 0.25 (without the egg file). Improvement has been seen by both lowering to about 0.15 and raising it to as high as 0.75.

Line 2: Mesh Movement Fixed Control Parameter (Optional)

This parameter sets distance outside of which elements are held fixed at their original locationd. It is a factor that is multiplied by the maximum boundary movement. The default is 7.0 (without the egg file or with only one line in the mov egg section). Improvement has been seen by both lowering to about 4.0 and raising it to as high as 20.0.
