bdf_set_force.set_load(ID, id_scales)

generate Load card

Parameters

• ID (int) – ID of load card to be generated

Returns

generated load card

Return type

card (pyNastra card object)

bdf_set_force.main()

main sequence

Input files:

• ‘mesh_property.bdf’: FEM model without force

• ‘LoadNodes.csv’: nodes where force imposed

• ‘forceStruct.dat’: force vectors

• ‘winggeom.ini’: wing geometry condiguration

Output files:

• ‘mesh_property_load.bdf’: FEM model with force

Procedure:

1. read BDF

2. read nodes to impose mechanical boundary conditions

3. read forces

4. dimensionalize force

5. set FORCE card

6. set LOAD card

7. export BDF

Parameters

• ID (int) – ID of load card to be generated

• id_scales (list) – lists of FORCE id and scale [[scale1, FORCE_id1], [scale2, FORCE_id2], …]

Returns

None

Danger

Parameters for dimensionalization are hard coded. They should be taken from input file or arguments.
