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.
