  1. work on your own with cfd/fem

    Good morning to all, I would like to ask for advice from those of you who have already done or thought about doing what I have in mind. I work as a cfd&thermal lead in a main contractor oil&gas Italian but for personal reasons I would like to leave this place because I do not digest it, I have...
  2. how to insert a damage criterion on ansys

    Hi guys, I need to insert the damage criterion on ansys, in particular a "max plastic strain equivalent" beyond which the program no longer takes into consideration that requested part and therefore excludes it from the calculation. Could you guide me? Thank you.
  3. problem bearing kisssoft

    Good morning to all, I have a problem with kisssoft or continue to give me warnings on the bearings, that is: "the minimum bearing load is not reached!" I'm trying anything that comes to my mind to solve the problem, but that's what's going on. I attach warning screens I thank you and wish you...
  4. rotational dynamics

    Good morning to all, I have to realize the dynamic simulation of the rotation of a crane, I am using solidworks simulation 2019 and I need to understand how to apply the load in question. I have already simplified the component with a single-dimensional element having the same stiffness of the...
  5. analysis fem cat5

    good morning to all, trying to make the fem of a tree with quarry for tongue subject to to torque (with cat) once created the mpc and applied the forces returns me the following errorI tried several times to redefine the mpc but the error remains present. . . Do you know what it can be due to?
  6. fem assembly nx

    Bye to all, When I try to create a new fem set, it gives me this mistake:I tried to activate blank templates in user preferences but this did not solve the problem
  7. distributed loads not constant catia v5

    Hello, I am trying to simulate the distributed load on a variable section beam on catia v5, until here I had no problem, however I can not understand how it can also make the load not constant but variable linearly. Does anyone know how I can do that? Thank you very much
  8. different materials

    Hey, everybody. I have a problem with ansys apdl. I practically have the classic dog bone test only which is formed by several different materials (bimetallic joint). I designed the structure on apdl but do not know how to insert the different materials in the different parts. Can any of you...
  9. simulation fem motor shaft

    Good evening to all, I am a university student of mechanical engineering. as part of a project I must carry out a fem analysis on a small motor shaft (diameter 8 mm). I wanted to know what the correct constraints are to be applied for static analysis. in fact I tried to bind the tree in various...
  10. libreria ansys - data source - pa 66 + 30gf - metal replacement

    Bye to all, I wanted to know if there is someone who has ever worked with a polyamide 6,6 (nylon 66) reinforced with glass fiber and if you can direct me to the characterization of the material in ansys. I am looking on the internet if there are material libraries to load, unfortunately I am not...
  11. estrudere "assembly"

    Bye to all, I am trying to achieve a structural analysis of a turbocharged car group. after drawing the parts (compressor, turbine, tree, spacers...) and creating the axieme (in the assembly) by binding the bodies between them, I should proceed by cutting 1/4 together to make the simulation only...
  12. welds in structural calculations

    Hello! I created a tank divided into 4 plates. the plates should be welded, but in the axieme I simply bound them with the coincidence, to which I wonder if in the analysis of the invertor stresses consider them as if they were properly welded or what? the point is that I was not able to weld...
  13. fem composite bicycle frame

    Hello everyone, I am a student of ing.mechanics and for a fem project for a university course I decided to do a static and dynamic analysis (simplified) of my olympiaiq monocoque racing frame (I am also a cycling enthusiast). I have reproduced the frame in solidedge, trying to respect the most...
  14. solidworks simulation o ansys

    hello to everyone, it's been a while since I use solidworks mainly for cad modeling. I noticed that among the various versions there is also the premium one with the possibility to do fem analysis. wanting to learn how to use a fem analysis software which would you recommend? solidworks...
  15. dimensional board

    hello to everyone, in a while I will have to size some lenses for butterfly valves. given the complex geometry I will rely on a fem analysis but I wanted to ask you if you think I can also make a numerical dimensioning (with calculations) of the simplified geometry (starting point to then...
  16. comsol dynamic mechanical simulation

    Hello everyone, I write to ask you advice on a problem that worries me for a few days: I am working on the design of a tactile sensor consisting of a silicone interface prepared for object manipulation. the problem is as follows: Before intervening with the practical sensorization of the...
  17. regulations and gmp for weld resistance with fem

    Hello everyone, recently asked me to check the resistance of a lifting equipment through European standards Eurocode 3 for steel structures. the structure in question is a welded frame mainly formed by square-section tubular bars. I would like to ask two questions: as it is necessary to make a...
  18. structural static analysis carpenters (fem) simulation

    often happens to do finite element analysis on carpenters type bases or machine structures, formed by many electro-welded iron plates (although often the welds are not inserted in the model), complete with various processes such as holes, fittings, bevels, plates of various thickness and put in...
  19. sftc deform

    Hello everyone, I am a mechanical engineering student at the last year and I would need (for my thesis) to perform ring rolling simulations with the fem deform 3d. However, the version in my possession (deform 3d v6.1) has problems with simulations in ring rolling. browsing the internet, I found...
  20. structural calculation

    Good morning to all, I hope not to open a debate already elsewhere. Would someone please tell me if they exist, and what are, regulations (international) to refer to for fem simulation? especially with reference to the calculation of machinery organs. Furthermore, is there a certificate body...
