Use the basin (cup) icon to run an optional pouring cup test to evaluate a material
that you want to assign to your model for a foaming simulation.
Location: Foaming ribbon,
Pouring Basin satellite icon on the Foam
Part icon.
The pouring cup test shows you how parameters
such as temperature and fill percentage can determine the foaming behavior of a
material relative to a particular mold shape. The simulated expansion of the foam
can help you determine the optimal conditions and material amounts to use in the
physical manufacturing of the foam part.
The pouring cup test is conducted
separately from the foam part setup and simulation. Run a pouring cup test before
loading your foam part model, otherwise you will be prompted to close your
model.
Hover over the Foam Part icon and click the
Pouring Basin satellite icon.
The default basin appears prefilled at 20%.
Use the microdialog options to define the basin and material, and to run the
test.
Microdialog option
Description
Select a shape for the pouring basin, then expand the
dialog and enter the dimensions for the basin:
For the cylinder, enter a radius and height.
For the cone, enter a bottom radius, top radius and
height.
For the cube, enter a length, width and height.
Specifiy the amount of material in the basin at the start
of the test either by mass (in units) or volume (as a
percentage of the basin capacity). The default prefill is
20% of the basin's capacity.
Click the View Materials button to open the Materials
dialog and review the material properties of your selected
material. You can also edit, import, export and assign
materials from this dialog.
Select a material for the pouring cup test. You can also
assign a material from the Materials dialog.
Enter the initial temperature for the selected foaming
material.
End time condition
Enter the desired duration of the test in seconds. The
default value of 300 seconds will usually be
sufficient.
Environmental HTC
Enter the environmental heat transfer coefficient for the
material.
Environmental Temperature
Enter the ambient temperature for the simulation.
Sensors
Click the to place one or more virtual
sensors in the pouring cup, if desired. The sensors will
show data from their location during the simulation.
Shape options
Click the chevrons to reveal fields that control the
dimensions of the pouring cup.
Click the Run button to run the pouring cup
test.
Select the completed run in the Run Status window.
Select a Stage and Result Type in the Analysis Explorer and review the
results.
