Thermal and Fluid Effects for Frequency Studies
Fluid pressure and temperatures can induce displacements, strains, and stresses that affect the modal characteristics of the model. The software considers thermal and fluid pressure effects for frequency studies. 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.
To include thermal effects for a frequency study:
-
In the Simulation study tree, right-click the frequency study icon and select Properties.
-
In the dialog box, click the Flow/Thermal Effects tab.
-
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).
-
Set Reference temperature at zero strain.
-
Click OK.
When you run the study, thermal effects will be considered.
To include fluid pressure effects for a frequency 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.
-
Use SolidWorks Flow Simulation to export fluid pressure data.
-
In the Simulation study tree, right-click the frequency study icon and select Properties.
-
In the dialog box, click the Flow/Thermal Effects tab.
-
Under Fluid pressure options, select Include fluid pressure effects from SolidWorks Flow Simulation and browse to select a file with extension fld generated by SolidWorks Flow Simulation.
-
Click OK.
When you run the study, flow effects will be considered.
