    basic FEA doubt

    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
  5. Hi manurico Yes, it is possible.

    Coating Modeling

    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..)

    add pressure to the edge of the 2d surface

    Hi dajeet You can apply pressure on an edge line as well. Change the selection to free edges and select the edge line.

    ERROR ID 266

    Hi NOOR ALAM ANSARI From the user profile window, change the Radioss version to 2017 and try again
  9. 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.

    Optistruct Steady State Heat transfer Analysis

    Hi Santhosh Ravichandran Refer tutorial OST: 1085, 1095 from OptiSruct help and check whether it helps.

    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

    Thermal Analysis

    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/

    Coating Modeling

    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.
  14. Hi mabefa After creating the load step, click on "edit" and then you have an option for entering temp load collector.
  15. Check this video also. See the load step creation after 8:00 min
