Generic Indicator for minimum element size (Mesh Adaptivity) #351

Closed somu15 closed 3 years ago

somu15 commented 3 years ago

Reason

Currently, the shear wave velocity indicator in MASTODON is restricted to soil simulations. A generic indicator would permit the user to input any desired material property as an indicator for the minimum element size marker.

Design

GenericMaterialIndicator class will be created to permit any material property the user desires to be the indicator for the minimum element size.

Impact

Among having other applications, this indicator class will permit fluid-structure interaction simulations where the fluid can have a significantly coarser mesh than the structure. Overall, this indicator may reduce the computational costs while preserving variable/auxvariable accuracies in the structural domain.
