Solution Layers
Solution-centric workflows allow you to traverse through modeling environments using a dedicated UI layer.
Manage Files and Data
Create, open, import, and save models.
Convert
Use the Convert tool to convert entire models between data types.
Geometry Modeling
Manage CAD, FE, and 2D parametric sketch geometry.
Meshing
Generate surface/volume mesh by defining mesh controls, or interactively create and edit 2D surface mesh.
Setup
Prepare your model and run the simulation.
Post-Processing
Post-process the simulation results by creating visualizations and measurements.
Automation
Automate simulation processes with templates and utility scripts.
Design Exploration
Once the baseline model is prepared, you can define morph volumes, morph geometry, create design shapes and run DOE studies. These tool work for both AcuSolve and ultraFluidX-based workflows.
Solver Help
More resources for AcuSolve and ultraFluidX solvers.

Cp (time-averaged)

Repeat Steps 1-5.
Note: Set the Z-Coordinate to 1.03571.Note: The value of 1.03571 pertains to the z-midpoint of the mirrors. You may calculate this value from the data contained in mirrors.csv, which was created following the steps in the Save Boundary Information section.
Middle-click to accept the changes.
Repeat Steps 6-13.
From the Post Browser, under Standard Output > Visualizations > Slice Planes, right click on the newly created Slice Plane and rename to Z-Slice Left Mirror Center.
From the Post Browser, under Standard Output > Visualizations > Clips, right click on Z-Clip Vehicle Mirror Center | and click Show.
