TOSCA Fluid.smooth

Note: For documentation of Tosca Fluid.smooth and more detailed information about how to use Tosca Fluid.post together with Tosca Fluid.smooth, consult the User Manual: Tosca Fluid.smooth.

Tosca Fluid.post writes results for Tosca Fluid.smooth into the optimization database. In addition, Tosca Fluid.post creates a Tosca Fluid.smooth parameter file (see User Manual Tosca Fluid.smooth) with default values for all Tosca Fluid.smooth required parameters. The file is named as specified on the Tosca Fluid.post command-line using the -o switch. If the default values are to be changed, the parameter file can now be modified using a text editor or loaded into Tosca Fluid.gui.

To write optimization results for Tosca Fluid.smooth, the format type SMOOTH can be used with the format command-line parameter (-f):

-f SMOOTH -i 1000 -o myresult

In this example, Tosca Fluid.smooth data is written for the optimization iteration 1000. The name of the Tosca Fluid.smooth XML parameter file is named:

myresult_01000_<result>_<cutoff_value>.xml

Note: Only one single cutoff value can be specified. A range of cutoff values is not supported for the SMOOTH format.

Important Note: It is strongly recommended to keep the name of the Tosca Fluid.smooth XML parameter file created by Tosca Fluid.post, since the chosen name is used to identify the result within the SIMULIA Tosca Fluid optimization database as well.

Length Units Treatment

Some pre/post processing tools do not provide the possibility to specify length units when a geometry file is to be imported. As a consequence the units in the STL file must fit to the units used in the CFD model.

To adjust length units, Tosca Fluid.post can scale the geometrical mesh data before it writes output files for Tosca Fluid.smooth. To scale the geometry, the --scale command-line argument can be used:

-f SMOOTH -i 1000 -o myresult --scale 1000

In this example, the geometry is scaled by a factor of 1000.
