# Torsion parameter (J) in sketched beams

## Torsion parameter (J) in sketched beams

Hello,

The calculation of the torsion parameter is feasible from any section of beam. This parameter allows the software to calculate the torsional stress seen by a beam section. Creo Simulate does not seem to calculate this parameter correctly if the section is obtained through a sketch.

Example :

The calculated parameter is :

• 9606.25 for standart beam (from library)
• 1.3e+06 for the sketched beam

Finally a gap of 99.3% between the 2 beams.

And stress are finally false.

Thank you,
