1. ## 2D Shell Composite - Differents BC for top and bottom layers

Hi, I made a surface composed of 2D Shell composite elements which represents a floor. How can I apply different boundary conditions for the top and bottom layers with a 2D Shell ? Basically I want to select independently elements from group 1 and elements from group 2 in the first picture. I have to attache some CONM2 masses on the upper layer that represent my objects attached on the floor. It seems impossible because I can only select the entire element (second picture). What is the solution for this case ? Thanks
2. ## Points in a different coordinates system

Ok thanks for the tip !
3. ## Points in a different coordinates system

Oh nice I totally forgot about that option ! Thanks for the rapidity ! Regards
4. ## Points in a different coordinates system

Hi, I'd like to create points in a different coordinates system than the origin one but I can't find the option. For example I create a marker, I orient it with angles compared to the origin, then I would like to create points in the coordinate system of the new marker. How can I do it without doing manually all the cosinus/sinus transformations ? Thanks !
5. ## Variable Point Coordinates

Hi, I try to make variable points coordinates using the VARVAL function but I always get "Error Evaluating". I basically created a Solver Variable (Value : Lin = 1000) and then I use VARVAL expression in the point coordinates, which points on the .id of the solver variable but always the same message "Error Evaluating". It works on Forces but not on points. I know it's possible in Adams so I think it's possible with Altair ! Thanks !
6. ## Bearing Stiffness

Ok thanks a lot
7. ## Bearing Stiffness

Hi ! I was wondering if the bushing element was a good way to design bearing stiffness (trans+rot) in MotionView ? If no what is the best way ? Thanks !
8. ## SPCF Not working

Hi ! I have a model in which I want to extract some forces in a truss, the problem is the SPCF/GPForce/MBForce are not working in the GLOBAL_OUTPUT_REQUEST Card. I can extract Disp/Stress/Strain but no Forces... No files are written (op2, h3d etc...) I'm in a transient simulation. Any idea ? Thanks !
9. ## Point To Curve

Thanks guys the problem was the number of points on the curve, I put 5 of them and it's alright !
10. ## Point To Curve

I'm not allowed to share my models but i created a very simple one with the same principle and the same issue... test.mdl So I guess I don't use the joint properly...
11. ## Point To Curve

I have two curves which are created with the entity curve, and these two curves are linked to each PTCV... Maybe it's not the correct entity for this kind of Joint ? I tried with Spline but PTCV can't detect splines when I have to select the curve...
12. ## Point To Curve

My curve (Joint1) is well referenced in the advanced joint, see pic below. That's why I don't know why it can't make any link between the PTCV and this curve... The model is made 2 PTCV and 2 curves (1 curve for each PTCV)
13. ## Point To Curve

Hi, here the log MotionView.log
14. ## Point To Curve

Hello ! I have a little issue, might be very easy to fix for you guys I want to create a point to curve joint, so I declare the two bodies, the point and the curve. But when I start the simulation I've got this issue : "ERROR: Param curve of PTCV joint [id=301001] not found!" Like it doesn't find the curve, but all seem to be well create (see pic) : the blue bar has to translate along the red line, simple as that ! The curve is defined as in the pic. I tried every combinations with the properties without effect... Thanks for the help guys !
15. ## Use of a Modal Force entity

Thanks for your answer, I'll take a look at this tutorial, I didn't see it spoke about my problem
