Running OSSmooth

To run OSSmooth from the command line, type:

ossmooth <prefix>.oss

To run OSSmooth from the HyperMesh solver panel:

1.	Select Solver from the Tools pull-down menu.

2.	Click the switch and select OSSmooth.

3.	After input file=, enter <prefix>.oss.

4.	Click solve.

Note:

OSSmooth standalone, which can also be invoked from the solver panel in HyperMesh, checks out 50 HyperWorks Units.

To run OSSmooth from the HyperMesh ossmooth panel:

1.	Select the ossmooth panel on the post page.

2.	Choose either OSSmooth (for geometry), FEA topology or FEA topography.

3.	Select the OptiStruct input file (<prefix.fem> and/or <prefix.sh> and/or <prefix. grid>) using the file= browser.

4.	Edit the OSSmooth input data by making selections on the screen.

5.	Click ossmooth.

OSSmooth (for geometry) will write a new <prefix.oss> file with the screen settings and load the geometry recovered into HyperMesh if the data format is IGES, STL, or Nastran. FEA topology and FEA topography will update the model in HyperMesh without outputting the result; if required, data can be exported from HyperMesh.

Note:

OSSmooth invoked from the ossmooth panel in HyperMesh checks out 42 HyperWorks Units (21 leveled and 21 stacked).

To run OSSmooth from the HyperWorks Run Manager:

1.	Select the .oss file using the Input file(s) browser.

2.	The Options field must be empty.

3.	Click Run.
