Hi everyone,

 

i am trying to insert a load combination of self weight and hydrostatic pressure on a dam.

Is it possible to change the load step of the hydristatic pressure in order to apply it after the self weight?

In bottom right corner i have the Tabular Data but i can't change the load step.

 

Thanks.

Can you make the acceleration 0 in the steps when you don't want any hydrostatic pressure?

Another way is to Deactivate the load in the steps when you don't want it active.

Are you going to add a hydrostatic pressure to the side walls as well as the dam?

Hi Peter,

Thank you for your reply.

No I can´t edit the Tabular data.

Can you explain to me how to deactivate the load in the steps, that would be my best option.

Yes I will have to apply the load to the side walls that are simulating the foundation of the dam.

 

Thank you veru much!

You just right click on one of the load steps and select Deactivate. This is a displacement example, but should work on an acceleration load.

Thnaks it worked just fine!

I've been trying to export the results using apdl commands, the displacements work well, however the stresses don't.

is it possible to export the stress results of the elements to a output file?

I have used the following apdl commends:

/Output, PH_stress, txt, ,

PRESOL,S

/Output

/Output, PH_disp, txt, ,

PRNSOL,U

/Output

 

Again thank you so much for your help!!

Right click on the Stress result and choose Export...
