Before Starting

Make sure you have a copy of the Simmetrix Simulation Application Suite and a pre-made model.

These tutorials were written using Build 050618 on Windows XP Professional.

Creating a Mesh

Simple Example

  • Open a the Simulation Application Suite (SimAppS)
  • Create a new project by going to File > New Blank Project. Select a name for your project and click OK.
  • Import your model by going to Import > Model File.... This will import your model into the Model section. You can view the model by double clicking on the model name.
  • To rotate the model, hold the ctrl key and left mouse button while moving the mouse. To zoom in and out, hold the ctrl key and right mouse button while moving the mouse. To pan, hold the ctrl key and the middle mouse button while moving the mouse.

  • Create a new Mesh Specification by going to Create > Create Case > Mesh Specification. Give it a name (such as case1) and select the model you would like to create a mesh.
  • Double click on the name of your model. Go to Selection > Select Model. This should select the entire model. To individually select a face, click the face. To select multiple faces, click the faces while holding Shift. Do deselect a face, click the selected face while holding Shift.

  • Double click on the name of your Mesh Specification found under the Attributes section. This should bring up the case for your mesh. Click on the attribute case.
  • Select Create Attribute > Mesh Size > Relative. Give a name to the attribute (such as size1) and a value. In this case a value of 0.1 is used. Using a smaller value will decrease the size and increase the number of artifacts.
  • Select Create Attribute > Mesh Curvature Refinement > Relative. Give a name to the attribute (such as curve1) and a value. In this case a value of 0.1 is used. Using a smaller value will decrease the size and increase the number of artifacts on curved surfaces.
  • Select Create Attribute > Minimum Curvature Refinement Size > Relative. Give a name to the attribute (such as min_curve1) and a value. In this case a value of 0.05 is used. Using a smaller value will increase the accuracy of the curvature.

  • Create a process by going to Create > Create Process > Surface and Volume Mesher > default. Give the process a name (such as proc1) and select the process interface meshCase Input. In this case it is called case1. You may leave the defaults for the rest of the values. Click Apply/Close.
  • Right click on the process created (proc1 in this case) and select Run Process.... This will bring up the process screen. Click Execute when you are ready. This will create your mesh. Press Finished when you are done.
  • You can view your newly created mesh by going to the Meshes section. Double click on the mesh name (mesh0 in this case) to view your mesh. Your mesh can be moved in the same way as your original model.

Refining Your Mesh

  • Create a new Mesh Specification by going to Create > Create Case > Mesh Specification and give it a name (such as case2) and select the model you would like to mesh. Click Ok when you are done.
  • Double click on your model name and select all the flat faces on the model. To individually select a face, click the face. To select multiple faces, click the faces while holding Shift. Do deselect a face, click the selected face while holding Shift.
  • Double click on your newly created mesh specification and go to Create Attribute > Mesh Size > Relative. Give it a name (such as size1) and a value (such as 0.5).
  • Go back to your model and select only the small curved faces.
  • Return to your mesh specification and go to Create Attribute > Mesh Curvature Refinement > Relative. Give it a name (such as curve2) and a value (such as 0.05).
  • Go to Create Attribute > Minimum Curvature Refinement Size > Relative. Give it a name (such as min_curve2) and a value (such as 0.025).
  • Go back to your model and select all the large curved surfaces.
  • Return to your mesh specification and go to Create Attribute > Mesh Curvature Refinement > Relative. Give it a name (such as curve3) and a value (such as 0.1).
  • Go to Create Attribute > Minimum Curvature Refinement Size > Relative. Give it a name (such as min_curve3) and a value (such as 0.05).
  • Create a new process by going to Create > Create Process > Surface and Volume Mesher > default. Give the process a name (such as proc2) and select the process interface meshCase Input. In this case it is case2. You may leave the defaults for the rest of the values. Click Apply/Close.
  • Right click on the process created (proc2 in this case) and select Run Process.... This will bring up the process screen. Click Execute when you are ready. This will create your refined mesh. Press Finished when you are done.
  • You can view your refined mesh by going to the Meshes section. Double click on the mesh name (mesh1 in this case) to view your mesh.
