The Modeler is where you do all the work of designing your FEA models.

The modeling process

The basic process for designing and executing a model in OnScale Solve is as follows:

  1. Import a CAD file & apply materials to geometry
  2. Apply physics constraints
  3. Run a simulation study
  4. View results

Each of these five steps is performed in a separate tab of the Modeler:

The navigation bar

At the top of all four tabs is the navigation bar. This lets you switch between tabs and it also provides access to the version menu. See Navigation bar.

Interface of the Modeler, Physics, and Simulator tabs

The Modeler, Physics, and Simulator tabs all have the following layout:

  1. Tree: Shows information about your model in a hierarchical tree format. See Tree.
  2. Toolbar: Each button on the toolbar is a tool that you can use on the Modeler or Physics tabs for selection or physic application. Not shown on the Simulator tab. See Toolbar.
  3. Properties panel / help: Shows the properties of whatever you have selected in the tree or the 3D viewer. Where nothing is selected, shows general help. See Properties panel.
  4. 3D viewer: Lets you interact and explore your model. See 3D viewer.
  5. Status bar: When OnScale Solve is performing an operation such as estimating or running a simulation study, shows this. Otherwise states how many core-hours of those allocated to this project you have used.
  6. View cube: Lets you precisely rotate your model. See Rotate.
  7. View bar: Includes buttons for viewing the underlying Python code, fitting the model to the available space in the 3D viewer, taking a snapshot and viewing settings which include toggles for viewing mesh, lighting and pins. See View bar.

If the design version is archived, or if a simulation study has already been run for the design version, you will not be able to make changes. A banner will inform you of this and prompt you to unarchive the design version or else create a new design version. For example:

Typical Simulation Workflow

The typical steps for creating a model and running a simulation study are as follows:

  1. Import a CAD file.
  2. Select a CAD part in the 3D viewer or the tree, and then assign a material to it using the properties panel. Repeat for all other parts in your model.
  3. Select the Physics tab.
  4. Select a face in the 3D viewer or the tree, and then apply a physics constraint to it using the toolbar. Repeat for all other physics constraints that you want to create.

    If you prefer, you can select a tool first and then select a face.

  5. Select the tab.
  6. In the tree, select Global Mesh to select the mesh settings.
  7. In the toolbar, select the Sensor icon to apply sensors.
  8. In the properties panel, select Launcher to learn the simulation time and core-hour cost.
  9. Once the estimation has finished, select Launch to launch the simulation study.
  10. Once the simulation study has been run, select View Results to view the results.
