### **Preprocess** For the component group of calculating the result pre-processing, the user can use the module under the group to set the symmetry constraint, material, optimization parameters, sensitivity options, multiple working conditions, and also collect the pre-processing parameters to connect the cloud server. * * * * * [](Symmetry.md) [**Symmetry**](Symmetry.md) Symmetric constraints. * * * * * [](Material.md) [**Material**](Material.md) Material settings. * * * * * [](OptParameters.md) [**OptParameters**](OptParameters.md) Optimize parameter settings. * * * * * [](PreProcessing.md) [**PreProcessing**](PreProcessing.md) Pre-processing parameter set. * * * * * [](Sensitivity.md) [**Sensitivity**](Sensitivity.md) Sensitivity option. * * * * * [](MultipleLoadCase.md) [**MultipleLoadCase**](MultipleLoadCase.md) Multiple settings. * * * * *
