  1. Hello, What is the difference between JOINTG Reaction forces and Element Stress (1D)? To what i have seen they dont match, when I extract one or another, their magnitudes are not the same? so, what of each of this mean? thank you!
  2. Hello, I have few questions regarding spring in optistruct. 1. How can I load a Cbush o cbush 1D? I know how to stablish the spring K but not a load. 2. Can I choose the direction of the load? Thank you!
  3. Hello, Today I have a simple question: for shell in Optistruct: Z1 = Top Face = Red Face Z2 = Bot Face = Blue Face Is this correct? Thank you!
  4. I did some research and saw on Altair Documentation that both Linear and Nonlinear models are solved by Direct Methods, Boeing Solver for linear static and MUMPS solver for nonlinear static, My understanding, and what I see on my .out file, is that nonlinear models are solved iteratively instead of direct as documentation suggests; So, my next questions are: 1) NonLinear quasiStatic is solved in an iterative or direct method? 2) What does the documentation mean that the default solver for non linear static uses a direct solver? Thank you!
  5. Hello Simon, Thank you for your quick anwer, I did some research and saw on Altair Documentation that both Linear and Nonlinear models are solved by Direct Methods, Boeing Solver for linear static and MUMPS solver for nonlinear static, My understanding, and what I see on my .out file, is that nonlinear models are solved iteratively instead of direct as documentation suggests; So, my next questions are: 1) NonLinear quasiStatic is solved in an iterative or direct method? 2) What does the documentation mean that the default solver for non linear static uses a direct solver? Thank you!
  6. Hello, Is there a way I can have control over how I want the model to be solved? Between Iterative and Direct Method? Can I have control on sparsity matrix? Thank you for your time!
  7. Thank you for your help Orasanna!
  8. Hello, I would like to know the center of gravity of a set of elements from my model. Currently I only know how to obtain the center of gravity but for the whole model (post--> Summary) But, how can I make this with a SET? thanks in advance.
  9. Thank you for your response! This was extremely helpful!_)
  10. Hello, What is the difference between CORD2R and CORD3R? What are their properties? If I reference joints to a specific coordinate system what would the difference be with CORD2R and CORD3R? Thank you!
  11. The pdf shared has the next error mesage: "This attachment is not available. It may have been removed or the person who shared it may not have permission to share it to this location." Thank you for your response Rahul!
  12. Hello, I am using an axial joint and want to to add motion to it. My questions are: 1) Which node moves relative to who? a. Node1 Moves and Node 2 Does not move b. Node 1 does not move and node move 2) If i was to assign a DOF = 1 in MOTNJG does this mean that the node moving wil move in the axial direction of my joint? Thank you!
  13. Hello, I have corroborated that Von Mises STRESS is output considering this formula, with principal stresses What formula does hypermesh uses for strain? Thank you!
