solid Module

All solid properties are defined in this file. This includes:

• PCOMPS
• PLSOLID
• PSOLID

All solid properties are Property objects.

Parameters:

size : int (default=8)

size of the field; {8, 16}

is_double : bool (default=False)

is this card double precision

Returns:

msg : str

the string representation of the card
