Hi,
how to map contact forces from Radioss solver to Optistruct solver and need to do Fatigue analysis by using those contact forces.
Regards,
Narasimhamurthy
to extract the contact forces from Radioss simulation and use them in Optistruct follow the procedure from the attached reference (page 32):
Thank you,
Tried this method. extracted contact force from Hyperview as shown in below picture.
force created by using linear interpolation option. but handle showing different values and direction.
<?xml version="1.0" encoding="UTF-8"?>
will it make peak force to average force depend on number for nodes? how to change direction of force?
Glad to help.
Extract the contact force vector (three components) instead of contact contour. Request contact vector output by eng/anim/vect flags CONT and PCONT.
The linear interpolation rules for input files have been changed (no comma allowed, separated by space or tab, only 3 coordinate components followed by vectors components):
for example:
Node Coordinates Vector(Contact Forces) 6647.1 -713.206 123.638 1.136E+01 -2.499E+00 -1.107E+01
Node Coordinates Vector(Contact Forces)
6647.1 -713.206 123.638 1.136E+01 -2.499E+00 -1.107E+01
Interpolation works best when the source mesh is geometrically similar to the target mesh.
