1. ## RBE 3 same dependent but different independent (for different load cases)

Hi agaon, I have a question, I have done both RBE definition with the dirrerent forces, but on the same dependent node, When i just xwant to use the X load for exemple, are the independent nodes for Z load inactive?
2. ## RBE 3 same dependent but different independent (for different load cases)

Yes exactly, I ll try this, Thanks a lot
3. ## RBE 3 same dependent but different independent (for different load cases)

Hi, I have different load cases applied at the same location, my problem is that i have to put different independent nodes from a same dependent note, 1 Case for a Z load 1 Case for a Y load 1 case for a X load Foe each case, the load will be applied on the same dependent node, but due to geometrie, the independent nodes will be different, i try to duplicate the node, but i can choose the node to take and apply the 2nd or 3rd load cases.
4. ## Mesh with nodes

I ll try this method, I ll report back the result Thanks a lot.
5. ## Mesh with nodes

Hi, sorry for the delay, I was working on other things. The ruled mesh works on "rectangle" surfaces thank you, but my concern is about the upper part of my part. However, i also find an alternative using fixed point, when i have put my nodes as i want, i create fixed points (geom/create/fixed point), i select the surface then the nodes. When the fixed point are created, the i create a 2D automech and it works. Concerning the upper of my part, when i use rules mesh, i have a meshing as follow (with a bad Quality index): See here after the meshing needed in order to study correctly the deformation ans constraints in this area Then, my concern will also be in how to create a medmesh thickness on this part, wich is evolutive as per sketch hereafter I was thinking about put the same thickness as a rectangle with average thickness. Then for my study, i ll have to remove material on upper side only (to simulate damage removal by blending in this area), and then check if the part support the ultimate loads, i was thinking about putting an ofset on the midsurface and then change the thickness with the needed value, or i do not know if it is possible to use 'morph handle", but it will be for later, i am not a this stage at all. Thanks for your support.

Sorry, i put them in PN G, Thank you for the remark
7. ## Mesh with nodes

Hi, Thanls for your answer, for my second mesh (usind 2D automesh), thickness assignment has been performed thanks My concern is that when i try to perform mesh (selectionning nodes created), it do not work, For a ruled mesh (i select the node in corner for 1st line then 2nd line the length , like if i want to perform a swquare), it says "one or more nodes appear in both input list, which hones i have to select? And For Spline, it do not follow the nodes when it mesh. I think, i do not choose the right nodes Thanks again for your answer. Pour meshage regle ruled.pdf splice node.pdf
8. ## Mesh with nodes

Hi, I am a beginner pon hypermesh and i have a question, how can i mesh using nodes i have already place? I send a picture for a better understanding. Then i do not remember how can i put thicknesses on midsurface? THanks you in advance 2018-05-13_13-08-01.pdf
