How to assign moment loads in a load step in hypermesh?
Please state on how to give the direction also.
Thanks.

Hi @Sam George
It is similar to how you do with FORCE loads.
Create Moment and refer the same as LOAD in loadstep.
Is there a way to solve this error? I have connected all dependent nodes on a single node( to apply force).
Please check if all the DOFs of an RBE2 element ( ID =2) is switched ON
Please use PARAM, RBE2FREE,YES will change ERROR 725 into WARNING 825,
Please share the .out file if you still face the problem
I couldnt find 'rbe2free>yes' in control cards - param.
Hi,
Please let me know what is the version of HyperWorks you are using.
I have attached the 'out' file. I couldnt find the rbe2free option in param card.
Also please tell a way to add two loads in a single loadstep, i have been trying, didn't work well.
Unable to find an attachment - read this blog
Hyperworks 14.0
The way RBE2s are modeled is wrong. Select multiple nodes as dependent nodes and center node as independent node. Apply loads on Independent node.
Apart from that there are issues with element quality. I corrected some and bypassed rest using PARAM>>CHECKEL>>NO.
Please run the attached file (Check the loads before you run)
Sir, I have given changes as told. can u please mention how to include force and moment in a single loadstep?
You can use LOADADD to combine two loads.
Create a load collector with loadadd as card image
is the card image as LOAD , cause there's no LOADADD card image.
Please make sure you are in OptiStruct user profile
Yes its Optistruct and I'm using HW14.0
I think its Load as card image, it asks for load num set , Data. Can i add it here?
Yes it is LOAD if you dont have any updates for 14.0
*** ERROR # 1996 *** in the input data: All entries have zero scale.
new error
Edit loaf card and provide scsle factor (S) as 1
The scale factor is 1 by default. Still the same error comes up.
Can you post an image of Load card?
I think i have added moment in the 'force' load collector. Don't know if i did it right..
I changed the S1 value to '1'.
Load should take moment as well.
Please post a picture of load card from your model
Make load set number to two instwad of 1 as you have force and moment and refer the moment here with scale factor for moment as 1
I have edited as told ,please check for any correction.
The card image for 'moment' is none. Only with 'forces' i have added 'moment' using LOAD card image.
I did the analysis, but the result doesn't reflect with the forces applied. Only moment deformation was shown.
The applied forces was high enough to show deformation, but nothing showed up.
Sam,
You got it wrong.
I said create another load collector not to edit the existing force
Force and moment without card image. Create another load collector with load as card image and refer both moment and force here. Use the same in loadstep
Thanks a lot. Sorry for taking too long to understand. Thanks again for your time.
Sam
