Error Found while simulating Convection (Heat Transfer)

Altair Forum User

Here I have send you the Error Message that I can see after Pre-Processing in Optistruct.

Can you tell me which steps I have to take care while doing convection and Conduction Simulation...

Thank you,

Regards,

Jay

Hi Nayak,

Looks like you did not apply a valid material/material card.

Please create a MAT4 card and refer the same in PCONV card.

Hey Prakash,

I already gave Temp 100 on top side and on the bottom side I have given 20 Degree cel. and I have select one Node in between my model and select as a 20 degree temp and make convection. I got error which you can see below pict:

Hi Nayak,

In CONV card ambient temperature is missing. Please correct this and try again.

I have already apply ambient Temp. As mention in OS- 1085, and I took SPCADD Card for two different temp Load Collector. Top 100 degree and Bottom 20 degree and in between I Chose one Point for ambient temp which has 20 degree temp and make convection.

Hi Nayak,

Slave set ID is missing in CONTACT card, please update and run again.

Altair Forum User

How can I edit Slave Set ID; I have seen in my Contact surface window but it doesn't Show anythings regarding Slave set..

It Shows only EID; GID1 and GID2 that I have already mention....

I got error like that : CONV ID ::::::: CONV ambient Point TA must be in SPC set of heat Transfer subcase.

I have taken one node for ambient temp and given it ID 1000000 and HEAT TRANSFER is my Load step....

Hello Friends,

I am doing Heat Transfer Analysis. I have both the cases- Convection and Convection. On the top of my Part there is higher Temp. Zone and there I have apply convection then High temp goes inside my Element and perform Conduction. Analysis also done with no Errors but I can't understand the result which I have found in Element Fluxes types. It doesn't make sense. It Shows my most of the part like Zero Heat flux... and I can only see top part has heat flux which has higher temperature.

Hi Nayak,

Can you check if there is any modelling issue?

How can I see/check the error from Modelling or not?
