FRDReader

class FRDReader(*args, **kwargs)

Reader for CalculiX FRD ASCII result files (.frd).

Supported element types include: HE8, PE6, PE15, TE4, HE20, TE10, TR3, TR6, QU4, QU8, BE2, BE3.

For datasets containing 6-component tensors (e.g. STRESS or STRAIN), this reader automatically pre-computes and appends the following derived scalar arrays to the output mesh:

• <NAME>_Mises: equivalent von Mises magnitude.

• <NAME>_sgMises: signed von Mises magnitude.

• <NAME>_PS1, _PS2, _PS3: principal components.

Added in version 0.48.
