Use the Conversion tool to convert an ANSYS file to an OptiStruct file.

1.Load the ANSYS user profile.
2.Import an ANSYS model.
3.To run the Conversion macro, from the menu bar, click Tools > Convert > ANSYS > To OptiStruct. The Conversion tab opens.
4.Click Convert. After the conversion, the OptiStruct user profile automatically loads.

 

Conversion Notes


All ANSYS solid and shell elements that are currently supported are included in the conversion tool.
Material properties – Thermal Conductivity, specific heat, thermal expansion co-efficient can be now converted.
Nonlinear material data and temperature dependent materials defined through TB tables are converted to TABLESx cards inside a MATS1.
2D and 3D Orthotropic properties of E, NU, and Alpha can be converted.
If components or properties do not have a material associated to them on conversion, then MID equal to 1 will be associated.
On conversion, a model will be cleaned by removing unused sets, ET types, and contact elements.
COMBIN14 elements are now converted to CELAS1 if key option2 for COMBIN14 in ANSYS is defined. If key option 3 is defined, it is converted to 3 coincident CELAS (1 per DOF).
Forces, Moments, Pressures, Temperatures and Constraints are automatically converted. MODOPT (control cards) will be mapped to EIRGL. ACEL (Control Cards) will be converted to GRAV.
Surface to Surface and Node to Surface contact pairs can be converted to OptiStruct. Contact element pairs CONTA173-TARGE170 and CONTA174-TARGE170 are converted to SURF (contact surfaces) in OptiStruct, and CONTA175 is converted to Grid SET. A CONTACT group for each contact pair is created during conversion.
Composite data conversion: ANSYS composite elements and layer information is converted to OptiStruct composite elements and composite property information.
BEAM44 element type, end release options defined in KEYOPTIONS 7 and 8 are converted to values in fields  PA and PB respectively in CBEAM card.
BEAM188 section properties are converted from the BeamSection Collector data and not from the EtType Sensor (this is how the BEAM188 section data is modeled in the HyperMesh ANSYS User Profile).
oSECTYPE with TYPE equal to BEAM and SUBTYPEs equal to RECT, CSOLID, CTUBE, I, L, T convert to a PBEAML property with corresponding standard section definition.
oSECTYPE with TYPE equal to BEAM and SUBTYPEs equal to ASEC, QUAD, CHAN, Z, HATS, HREC convert to a PBEAM property with corresponding cross section property values.
MPC184 converts to either a RBE2 rigid element or a CBUSH/PBUSH bushing element depending on the KEYOPT(1) value, as follows:
oKEYOPT(1) equal to 0 converts to RBE2 with constraint DOFs equal to [123]
oKEYOPT(1) equal to 1 converts to RBE2 with constraint DOFs equal to [123456]
oKEYOPT(1) equal to 6 converts to CBUSH + PBUSH
K4 equals <blank>/0.0
K1, K2, K3, K5, K6 equals RIGID
oKEYOPT(1) equal to 8 converts to CBUSH + PBUSH
K1, K4, K5, K6 equals <blank>/0.0
K2, K3 equals RIGID
oKEYOPT(1) equal to 9 converts to CBUSH + PBUSH
K2, K3, K4, K5, K6 equals <blank>/0.0
K1 equals RIGID
oKEYOPT(1) equal to 10 converts to CBUSH + PBUSH
K1 equals <blank>/0.0
K2, K3, K4, K5, K6 equals RIGID
oKEYOPT(1) equal to 11 converts to CBUSH + PBUSH
K1, K4 equals <blank>/0.0
K2, K3, K5, K6 equals RIGID
oKEYOPT(1) equal to 12 converts to CBUSH + PBUSH
K2, K3, K4 equals <blank>/0.0
K1, K5, K6 equals RIGID
oKEYOPT(1) equal to 13 converts to RBE2 with constraint DOFs equal to [123456]
oKEYOPT(1) equal to 14 converts to RBE2 with constraint DOFs equal to [456]
oKEYOPT(1) equal to 15 converts to RBE2 with constraint DOFs equal to [123]

 

Assumptions

The Conversion tool only converts entities imported by the ANSYS FE input reader.
For shell elements, constant thickness parts are assumed.
Analysis types assumed: Static – gravity, forces, pressures and constraints; Modal.
