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.

Cf (Time-Averaged) – Narrow Range

From the Post Browser, under Boundary Collections > Flow Boundaries, right click on Vehicle and click Edit.
The Display Properties Dialog – Surface Coloring Tab opens.
Set the Legend range from 0 to 0.003.
From the Display Properties Micro-Dialog, switch to the Contour Line Display tab (third from the left on top).
Set the Display value to 7.
Set the Contour Range from -0 to 0.003.
From the Boundary Groups Guide Bar, click on the green check mark to accept.
