Hi, the TBDATA command can only take six values per command: https://ansyshelp.ansys.com/account/secured?returnurl=/Views/Secured/corp/v222/en/ans_cmd/Hlp_C_TBDATA.html

You can specify values for up to six constants per TBDATA command. Issue the command multiple times if needed.

So, to define eight constants do this:

TBDATA,1,prop1,prop2,prop3,prop4,prop5,prop6

TBDATA,7,prop7,prop8
