To learn more about Inventor Nastran, visit our extensive training courses or feel free to get in touch with Symetri. Always use Solver Offset Bonded contacts for models converted to surfaces using either Find Thin Bodies or Midsurfaces. Always use Shell elements when you have thin models with a ratio of 1:30 or above (1mm thick and 30mm long).ġ0. This will remove the need to add contacts between individual surfaces.ĩ. Use Continuous Meshing when using surface models and shell elements. This will remove the need to define split faces required to correctly define the load-bearing faces.Ĩ. When analysing bolted connections within Inventor Nastran you can include washers from the inventor environment.
You can use Ground Plane settings to display half model results as full model.ħ. You can define symmetry conditions, using frictional constraints.Ħ. Note the maximum value needs to be in the same place.ĥ. If the difference in value is less than 10%, you can assume convergence has been achieved. You can achieve mesh convergence by checking Corner and Centroidal Data Type results. You can then release the desired rotational degree of freedom to simulate a pin connection.Ĥ. So, for example, if you need to simulate a simple supported shaft, you can define rigid body connectors on the desired locations and then select the point for assigning constraints. Solid elements do not allow rotational degrees of freedom. This can be significantly reduced by changing the WARNING parameter value to OFF.ģ. Typically, when you run Inventor Nastran, many warnings can appear, resulting in large output files. To enable Nastran to use all your computer’s cores for faster solution times, change the NPROCESSORS parameter value to your computer's maximum number of cores.
