What is the difference between internal and external fans?
My model has 100,000 elements, how much RAM and disk space do I need to solve the model?
Is there flow through the hub of my fan?
How do I incorporate a swirl effect into my fan flow?
Can I use plates on cabinet walls?
What is the difference between plates and walls?
How do I specify a non-uniform conductivity to my blocks or plates?
I am specifying power on a block. Can I specify the power to the volume as well as to the faces?
When I write out an IGES file from IDEAS, Icepak can not read it. How can I fix this?
Is it possible to copy one object type to another?
What is the difference between "Total heat" and "Fixed value" in "Model/Source"?
I am using a source to fix the temperature on a block, but I am not getting the right result. What is
happening?
How do I calculate the thermal resistance given conductivty data?
My Icepak model is so cluttered, what should I do to see the model more clearly?
You can suppress the views of some objects. See the next FAQ on suppressing views for how to
do it. You can also use the "Gouraud shading" on a given class of objects (or just one object) to see
these objects clearly.
How can I suppress the view of objects in Icepak?
At the top right hand corner of the Icepak interface, there are two columns of boxes. Click on
"Visible" and toggle off the object type (e.g. blocks) the views which you want to supress. Note
that the object class that is suppressed is still part of the model, it is just not visible. For that
reason, it is a good practice to toggle on these objects (after you are finished viewing) so that you
don't forget about them. You can also suppress the view of a particular object (rather than a class
of objects) by editing that object and selecting "Invisible" under "Shading" in the object edit form.
Sometimes the dimensions of objects contain too many decimal places: Is there a way to
avoid this situation?
Before beginning to build your model, set the "x-grid", "y-grid" and "z-grid" to the minimum
decimal place you want to have (for example 0.0001). This will force objects to move or locate
with fixed increments and you will not get the unwanted decimals unless you scale the model.
How do I move, copy or scale a group of objects at the same time?
Use the "Groups" option in the "Model" menu to group the objects. You can then move, copy, or
scale as you wish. Please refer to the training notes or the Icepak manual for more details.
How do I move a group of objects using the mouse?
Use the "Groups" option in the "Model" menu and group the objects. Then toggel on the "Move
group" button and move the group using the mouse (shift + middle mouse button).
How can I change the specifications (material type, power, etc.) of a group of objects in my
model?
First, group all the objects. Then change the specifications of one of the objects. Then use the
"Copy parameters" option in the "Groups control" form to copy the specifications from that object
(which is highlighted in the Icepak edit form) to all other object in the group. You will see the
following messages in the messages window: Copying parameters from ... to ...
What is a part?
A part is an assembly of objects which you create and store that can then be used in different
