an enhanced region command
| Parameters: | * regTag (int) - a predefined or new region tag. |
|---|---|
| * '-ele', e1, e2, ... (int) – the region is defined by elements e1, e2, .... If no tag is given, then all elements are added. | |
| * '-eleRange', e1, e2, ... (int) – the region is defined by elements in the range [e1, e2]. | |
| * '-node', nd1, nd2, ... (int) – the region is defined by nodes nd1, nd2, .... If no tag is given, then all nodes are added. | |
| * '-nodeRange', nd1, nd2, ... (int) – the region is defined by nodes in the range [nd1 nd2]. | |
| * '-rayleigh', alphaM, betaK, betaKinit, betaKcomm (float) – arguments as in rayleigh command. | |
| * '-getNodeTags' (str) – return all node tags in the region. | |
| * '-getConnectedEleTags' (str) – return all elements that connect to all nodes in the region. | |
| * '-getEleTags' (str) – return all elements that are added by mesh/remesh commands. | |
| * -mass', m1, m2, ...' (float) – set the nodal mass for all nodes in the region. | |
| Returns: | a list of node or element tags if ‘-getNodeTags’, ‘-getConnectedEleTags’, ‘-getEleTags’ are specified, otherwise, returns None. |
| Return Type: |
list(int) or None |
