Hello,

I am using Ansys 14.5.0

I want to apply pressure loads on six surfaces [non-planar] to simulate wind [normal-to-surface direction] and snow loads [projected in gravity direction].

For normal-to-surface direction-
There is an option 'Normal to' in the 'Pressure' feature. I am not sure whether this will apply the pressure normal to each of the selected surfaces or normal to only first surface in the selection. In the pressure visualisation, only one arrow is shown and it is normal to first surface selected.

For projected in gravity direction-
Is there an option in Workbench to apply such type of loads?

Regards,
Sushant

Yes.

Yes.
See the ANSYS help for hydrostatic pressure.

Hello,

Thanks for your answer with the confirmation that pressure is applied normal to each of the selected surfaces when the 'Normal to' feature is used.
I checked the ANSYS help for hydrostatic pressure and could not find any information on application of projected loads (eg. snow load on an inclined roof). I came across SURF154 element in the ANSYS help which states that projected loads can be applied using keyopt(11) set to 1. But I don't know where to locate the SURF154 option in Workbench. Is it possible to use these elements directly in Workbench or APDL commands are needed? If it's only by commands, do you have a reference code for use of SURF154 to apply loads in Workbench?
