Fan questions in Caedium

Hello.

I am trying to model a fan entirely within my flow volume.

Internal fluid flow

bseaborn — Mon, 22 Jul 2019 12:29:21 +0000

Does anyone have experience simulating internal fluid flow through a cylinder with internal baffles and side exit holes? I want to see how the fluid acts inside and outside of the cylinder. I can't seem to get the fluid to come out of the exit holes when the holes are capped.

Problems with import of Solid Edge file into Caedium

Optimine — Sat, 29 Dec 2018 12:50:22 +0000

We are a F1 in schools team and have not worked with Caedium before. We wanted to assess several models we have created in solid edge. We understand, that we should either use the format type .igs or .step. We believe we have created these files in solid edge, but when trying to import them into Caedium we always fail. Can anybody help us - what are we doing wrong? Many thanks in advance!

Using inlet fan option and outlet fan option

PeterG — Thu, 04 Oct 2018 23:35:58 +0000

Hello.
I am working on a simulation in which I have both inlets modeling fans and outlets modeling fans.
The simulation runs fine and converges well when I have both the inlets and outlets set to fixed velocities that are surface normal. However, I do not get pressure readings that are realistic at all (well beyond what the fans are actually capable of generating).

Can I simulate centrifuge with no inlet or outlet?

I want to spin a closed system with no flow in or out. Will this simulate?

How do I set the RPM rate of the system and how many times it spins?

Hey,

Ich muss für Formel 1 in der Schule mein Auto im Windkanal testen. Das Auto wurde in Solid Edge konstuiert und ist eine .asm Datei. Ich möchte diese nun in Caedium öffnen. Wie mache ich das?
Ich bitte euch um eine schnelle Antwort.
Danke schonmal im voraus.

Home workstation for Caedium - Question about Caedium processes

PeterG — Fri, 26 May 2017 18:11:21 +0000

Hello Dr. Smith,

I am considering purchasing a new workstation for Caedium.
As I understand it, mesh generation on Caedium uses but one core of even a multi-core computer, so a single (or fewer) core computer with faster processor core speeds is more helpful for mesh generation, whilst having many more cores is more helpful for solver running, even if the processor speeds are slower.

Question about fan inlet and fan outlet with compressible flow

PeterG — Thu, 27 Apr 2017 17:13:24 +0000

Hello.
I have a simulation involving subsonic compressible flow and a fan inlet as well as a fan outlet.
How can I use both compressible flow and a fan inlet and fan outlet?

When I changed the simulation from incompressible flow to compressible flow, the option for fan inlet/outlets disappeared from the inlet/outlet properties menu.

Importing faces that are not put into volumes

ken — Wed, 12 Apr 2017 20:19:02 +0000

I would like to import faces without them being put in volumes. With this I can collect them in order and group them later once I combine them all into one volume.

Or, if I import them as a volume how can I break them from the volume?

Thanks

Unexpected process exit

ken — Thu, 09 Feb 2017 23:22:35 +0000

I am venturing in to using radiation and a simple model of a room with warm body in it runs very well in heat transfer however when I engage radiation it fails.

The failure occurs at the time when the program was to update the image and gives and stops cold and give this

Warning:
volume [www.1836.5] RANS Flow; Failed
Unexpected process exit.

Any fixes for this?

Setup of Transient Time Values

ken — Wed, 11 Jan 2017 23:13:26 +0000

I am having trouble understanding the set up of the Simulation's "Duration" and "Increment" values and the Volume's "Time Step" and "Iterations" values.

I have read through the transient example several times but I am yet confused.

Can you define each of these four items and how they relate? I noticed in examples the Simulation's Increment value is not defined.

Time Variant Flow Setup

ken — Mon, 22 Aug 2016 15:25:20 +0000

I am trying to set up a time variant flow at a face but it is not clear to me how set up the values in the parentheses. For example, I am using units of minutes and feet. I want to set up the flow to be zero for 15 seconds then have a vertical flow rate of 250 ft/min after 15 seconds.

Are the units that are used in this field the same as my IP units?

How do I structure the input?
