Flow and Thermal Effects for Buckling Studies

The software considers flow pressure, generated by SolidWorks Flow Simulation, and thermal effects for buckling studies. Slender parts subjected to temperature rise, like electronic components, can buckle due to restrained expansion. For thermal effects, you can specify a uniform temperature rise, assign different temperatures to different regions in the model, or import a temperature profile from a thermal study.

When using the Input temperature option, make sure to specify temperatures on components or shells. Specifying temperatures on the boundary only may not be practical. You may need to create and solve a thermal study first to compute temperatures at all nodes.

To include thermal effects for a buckling study:

  1. In the Simulation study tree, right-click the buckling study icon and select Properties.

  1. In the dialog box, click the Flow/Thermal Effects tab.

  2. Under Thermal options, select one of the following options:

  • Input temperature. Uses the prescribed temperatures defined in the Load/Restraint folder of the study to calculate their effects on the buckling of the model.

  • Temperatures from thermal study. Uses a temperature profile resulting from a completed thermal study. The thermal study can be steady state or transient. If you check this option, you need to specify the Thermal study. And if you select a transient study, you need to specify the Time step.

  • Temperature from Flow Simulation . Reads the temperature profile resulting from a completed Flow Simulation on the same configuration from a file. Browse to select the FloWorks Result Files (*.fld).

  1. Set Reference temperature at zero strain.

  2. Click OK.

When you run the study, thermal effects will be considered.

To include fluid pressure effects for a buckling study:

SolidWorks Flow Simulation is needed to generate the data. Once the file containing the data becomes available, SolidWorks Simulation can read the data to consider the fluid pressure.

  1. Use SolidWorks Flow Simulation to export fluid pressure data.

  2. In the Simulation study tree, right-click the frequency study icon and select Properties.

  1. In the Buckling dialog box, click the Flow/Thermal Effects tab.

  2. Under Fluid pressure options, select Include fluid pressure effects from Flow Simulation and browse to select a file with extension fld generated by Flow Simulation .

  1. Click OK.

When you run the study, flow effects will be considered.
