  1. Should I uninstall?
  2. Hi George. It hasnt worked unfortunately. Any other idea? Thank you beforehand.
  3. Hi everyone. I am doing some simulations for my dissertation project and during meshing and computing processes the Hmopengl.exe process stops working. I have tried to figure out whats going on but everything I have done has been useless so far. I have given administrator rights to the application, disconnected the anti-virus, changing the work directory but nothing has changed. Sometime I receive an extra error saying "segmentation error ocurred". I have plenty of space in the hard drive and the working directory has around 100gb space. I will upload some pictures later with the problem. Thanks in advance. Guillermo
  4. Hi everyone, I am designing a gearbox housing, and from the contact points from the gears I am creating nodes, applying forces and creating rigids to transfer the load to the faces of the bearings. But during the simulation, I am getting the error 173. So I understand that from the same node I cannot link two different rigids. I have seen some posts and how to solve it, but I think my dobut now is more on the procedure I need to follow to solve it, si what I have tried seems it havent worked. I have read that I need to create another node to avoid dependencies, so: I created another temp node, I applied new forces to that node, I created Rigids from that node to the faces where I want to apply the forces. But as I said, I am getting the same error. I have attached the model if anyone wants to take a look: https://www.dropbox.com/s/8x173c58cpjl1y4/5.hm?dl=0 Thank you beforehand, Guillermo
  5. Image Crashed after simulation

    Thank you, I solved the problem!
  6. Image Crashed after simulation

    Hi Rahul, I though that making a 3D mesh would be enough. I couldnt find a mesh connection tool. Is it inside any other feature into the mesh section? or where I could find any info about? Thank you beforehand, Guillermo
  7. Image Crashed after simulation

    This is completely right! I missed that, I always mess with the units conversion. But what is true is that I kept a relation between forces, so everything is in the same scale. The forces that I have input are in N, so they are correct, therefore I dont know what I am doing wrong. If somebody could check the model I would appreciate that. Find attached the file. 2.hm
  8. Image Crashed after simulation

    Hi Rahul, I measured it but the mass is really low, 1 gram... Do you know whay is that happening? I attach you the model. Thank you beforehand, Guillermo 2.hm
  9. Hi everyone, I am buiding a model from a Solid component, so I created a tetramesh and a PSolid property (see picture 3). The simulations goes well, but when I try to open it then I get the other two pictures when I display anything and then when I apply the contour. Something I discover is that I have different components in the model, so when I apply the forces to the different components they start to dissapear, until I apply the force to all of them so this happens. I dont know if the problem is from the set up o from HyperView, but could be both. Any idea about this? Thank you beforehand Guillermo
  10. Thank you very much for your reply, I will take that into consideration!
  11. Hi everyone, I am doing a project for the subject of aerodynamics and I am using AcuConsole for that. I am finding some problems with the CATIA reader I have installed with AcuConsole, so I am thinking now switching the file format to stl (seems more reliable). The problem I am finding now is that I cannot split the model into different surfaces, to assign the airfoil, the sides, etc. I tried to divide the geometry with the feature angle, changing it from 90 degrees to 0.1 and doesn't allow me to pick up any geometry when I create a new surface group. Could you help me to solve that problem? I attached the files if anyone wants to try. Thank you beforehand. Guillermo Flow Domain.stl
