Before setting up your analysis, consider the following:
When modeling stranded conductors using SOLID236 or SOLID237 with KEYOPT(1) = 0, the applied current density J specified on the BFE command (BFE,,JS) must satisfy the solenoidal condition . For more details about the solenoidal condition, see Analysis Considerations.
In transient electromagnetic with electric potential (VOLT) degree of freedom using SOLID236 and SOLID237, the THETA integration parameter is set to 1.0 by default. To overwrite this default, issue the TINTP command.
