Starting Tosca Structure.smooth

Tosca Structure.smooth prepares the optimization results for import into a CAD system or FE-preprocessor to be remeshed and used in a validation run.

This task shows you how to:

Start Tosca Structure.smooth in the Tosca Structure.gui

Context:

There are two ways to define a Smooth task in the Tosca Structure.gui:

  1. Using the Tosca Structure.pre editor: Insert a SMOOTH command block in the normal Tosca Structure optimization parameter file as shown in the figure below. If defined like this, Tosca Structure.smooth is called automatically once the optimization ends. Multiple SMOOTH blocks are allowed in the same parameter file resulting in Tosca Structure.smooth being called multiple times.

  2. Using the dedicated Tosca Structure.smooth editor: A stand-alone execution of Tosca Structure.smooth can be started from the corresponding editor like shown in the figure. Simply load in the optimization results to use, optionally modify the default settings and click the Start Smoothing button.

    Tosca Structure.smooth can be rerun like this with modified parameters to obtain the desired results. The button View Result opens a dialog for the resulting VTFX file to be opened in Tosca Structure.view.

  3. In addition, you can start Tosca Structure.smooth without a graphical interface directly from the command line using the following command: 

    ToscaStructure post --smooth --opt <smooth_parameter_file>.par --job <tosca_job_directory>

    A suitable parameter file has the format

    
SMOOTH
<parameter1> = <value1>
<parameter2> = <value2>
END_
    Note: Manually creating the parameter file from scratch requires some experience. It is recommended to use and modify an earlier smooth parameter file created with the Tosca Structure.gui. In most cases, then only the paths to the result files must be changed.
