Specify the frequency at which criteria for each component are checked during solution (NLADAPTIVE,,ON).
VAL1
controls the checking frequency:
If

VAL1
< 0, the program checksVAL1
number of times distributed evenly throughout the load step or defined time interval.
Default: VAL1
= -1
For mesh-quality-based criteria, it is good practice to check the criteria at every
two substeps. To exploit the accuracy property of the hex-dom meshes, however, you can
control the first time point and the range for checking via
VAL2
and VAL3
arguments.
Criteria-checking does not guarantee that remeshing occurs at a given substep. A new mesh is generated for the component only if any element meets the criteria assigned to it.

Because nonlinear adaptivity does not control the substep length (solution points), it cannot accurately control the number of splitting or remeshing points. For frequency checking
