Hi all,  
I’m new to CalculiX and PrePoMax. I tried to apply a time-varying pressure load such as `p=1000sin(t)` on a boundary in PrePoMax. It seems that PrePoMax doesn’t support such function and the `Imported pressure` needs to provide OpenFOAM results.

 ![PrePoMax_pressureBC](https://global.discourse-cdn.com/free1/uploads/calculix/original/2X/e/ec27bb00e87398d7eb72e7e22937ad754bd2b7d8.jpeg)  
How could I apply such a time-varying pressure load? Could CalculiX read pressure time history files to apply loads to boundaries? Any hints will be appreciated!

Best regards,  
Stan

You can use the amplitude feature for this purpose. Check it in the documentation. But you will have to provide the data in tabular form (time vs amplitude).

Hi @Calc_em ,  
Thank you for your reply! I’ve read the documentation about keyword `amplitude` and tried to apply the load `p=10000sin(t)` for simulating two seconds. The tabular I set is as follow:  
 ![tabular1](https://global.discourse-cdn.com/free1/uploads/calculix/original/2X/7/728ee3d9c2a17a25cb33ee6a1bb7a244e44f24e3.png) ![tabular2](https://global.discourse-cdn.com/free1/uploads/calculix/original/2X/7/7fd6e1eeba742f8a3ad8928fcac9c971dd52fd60.png)  
And then, a uniformed pressure 1Pa is applied on the left boundary. If I understand right, the actual load on the boundary is the product of the uniform pressure and the amplitude.

 ![Load](https://global.discourse-cdn.com/free1/uploads/calculix/original/2X/8/88154f75d1d5faf7fbbe08096e424d555cab7293.png)  
Besides, what kind of step should I use for such simple case and how can I set the simulation time to two second? I guess I should use `Dynamic step` but there is no such type in PrePoMax.  
 ![Step-1](https://global.discourse-cdn.com/free1/uploads/calculix/original/2X/1/10b7080a955227cb23ab678d6125bc4c7d80bd08.png)  
Thanks in advance!

Yes, the magnitude of the load is multiplied by the amplitude.

You can set time step for a static step to 2 s (if you change the incrementation type) but this procedure doesn’t use physical time - it’s just a measure used for load incrementation. If you want to account for inertia effects and physical time then you need a dynamic step. It’s not yet implemented in PrePoMax but you can define it by editing keywords manually.

Thanks again for your generous help!  
I exported the .inp file from PrePoMax and used a dynamic step with 2s. However, it seems that the load is not multiplied by the amplitude since the displacement in x direction is quite small.

 ![Dynamic_2s](https://global.discourse-cdn.com/free1/uploads/calculix/original/2X/d/d57ceaec1df35775cf04c8eb2cc33baa3b52fcf8.png)  
If you have some free time, could you please help me check out the input file to see what is going wrong?  
(Since the file cannot be uploaded directly, I seperate it to several parts using Hide details)  
Thanks!

You also have to select the amplitude when defining the load.

To make sure that the amplitude is working as expected, compare the sum of reaction forces from the fixed node set with the applied load.

To share the whole input file it’s best to place it in a preformatted text block (Ctrl+E) or place it on some hosting website like OneDrive, Google Drive or WeTransfer and share the link here.

Hi @Calc_em ,  
Thanks for your help! I’ve managed to run the simulation according to your suggestions. The results seem to be fine. 😄  
By the way, I’ll follow your advice to share the input file next time.

Best regards,  
Stan
