  1. Hi migid You can open the animation files individually also. The animation files (A01, A02, etc) will be written in the run directory. If this was not what you asked, can you please explain more about your need
  2. Hi Ahmed For Cylindrical Coordinates 1 - Translation in the radial direction 2 - Translation in thetha direction 3 - Translation in the z-direction 4 - Rotation in the radial direction 5 - Rotation in thetha direction 6 - Rotation in the z-direction For a cylindrical coordinate system a single unconstrained node can translate axially along Z, translate radially along R and swing circumferentially about θ. So to apply a constraint to Z and R will allow the point to move in θ only
  3. Hi Shi Feng Can you please share the .OUT file
  4. Hi Yash Gaikwad The error is because the slave nodes cannot detect the master segment. The master segment is found via 2 formulations: Old formulation New improved formulation Change the Isearch formulation to "old segment" and this the analysis will run without any error. Go to Tools > Model checker to check for other errors. Check online help for more details regarding Tied 2 interface and formulations.
  5. Hi Shi Feng Can you please share the model file
  6. Hi GAJENDRA KUMAR NHAICHANIYA Thanks for the update. I will try and update you with a better solution.
  7. Hi GAJENDRA KUMAR NHAICHANIYA In your model, you have given a thickness of 0.1 mm. Can you please confirm this whether its 1mm or 0.1 mm.
  8. Hi GAJENDRA KUMAR NHAICHANIYA Some modifications have been done. Check whether this helps you. 1. The lower thickness value may cause it to vibrate due to the imposed displacement. So it has been increased 2. A negative value is provided in the gravity curve to denote that the gravity is acting in the - Y axis 3. constrains were provided to the base to restrict the movement in other direction expect in X flask.hm flask_0000.rad flask_0001.rad
  9. Hi bn_abhi This is due to wrongly assigned property for shell elements. Check whether you have used the card image PSHELL for shell elements and PSOLID for solid elements
  10. Hi mpvnaresh You can use 2D > elem offset for creating a stack of solid elements If you want to get better results it is advisable to use exactly the same material properties you are using.
  11. Hi dineshagrawal115@gmai It is not paid service. If you are a student, apply with your institution details and it will be approved
  12. Hi Register here and once the admin approves, you can access it https://certification.altairuniversity.com/login/index.php
  13. Hi Saravanan R Here limited no: of nodes means finite no of nodes. Any continuous object has infinite degrees of freedom and it is not possible to solve the problem in this format. The Finite Element Method reduces the degrees of freedom from infinite to finite with the help of discretization or meshing. All of the calculations are made at a limited number of points known as nodes. The entity joining nodes and forming a specific shape such as quadrilateral or triangular is known as an Element. To get the value of a variable (say displacement) anywhere in between the calculation points, an interpolation function (as per the shape of the element) is used The word "interpolate" in general means to "insert (an intermediate value or term) into a series by estimating or calculating it from surrounding known values". The same thing is done in FEA also as mentioned above This is clearly mentioned in this e-book. Have a look at this (https://altairuniversity.com/free-ebooks-2/free-ebook-practical-aspects-of-finite-element-simulation-a-study-guide/). Refer page 21-33 where it describes how the results are Interpolated from a few calculation points
  14. Hi mfr You can use elem offset option from 2D> elem offset. Then you have to create faces along the grey colour mesh (turbine solid mesh) and use that to create offsets. Similarly, you can create all other layers ( orange, blue..)
  15. Hi dajeet You can apply pressure on an edge line as well. Change the selection to free edges and select the edge line.
  16. Hi NOOR ALAM ANSARI From the user profile window, change the Radioss version to 2017 and try again
  17. Hi j8jang That depends on whether your material goes into a non-linear condition or not. According to tsai-wu criterion, the material is assumed to be elastic until the Tsai-Wu criterion is fulfilled. After exceeding the Tsai-Wu criterion limit the material becomes non-linear. If the material exceeds the elastic state and passes into non-linear state then it is compared to a maximum value F(Wp) varying in function of the plastic work during work hardening phase. so here for comparing with F(Wp) you need to input "b", plastic hardening parameter and "n", plastic hardening exponent. So in your case, I feel its better to input "b", plastic hardening parameter and "n", plastic hardening exponent.
  18. Hi Santhosh Ravichandran Refer tutorial OST: 1085, 1095 from OptiSruct help and check whether it helps.
  19. Hi rahul rao Is it possible to share the model file?. You can use secure link if needed https://ftin.india.altair.com:8443/filedrop/~Ma3TaE 
  20. Hi AdrianoP I suggest you can go through the thermal e-book which will give you a better understanding https://altairuniversity.com/free-ebook-thermal-analysis-with-optistruct/
  21. Hi mfr Did you mean how to model a three-layered thermal barrier coating? Also can you please explain what type of analysis you are about to perform.
  22. Hi mabefa After creating the load step, click on "edit" and then you have an option for entering temp load collector.
  23. Check this video also. See the load step creation after 8:00 min
