1. ## Problems with Fatigue Analysis

Hey guys, I’m a mechanical engineer student and I participate in a project where I analysis the structure of a modern tricycle. I need help with the fatigue analysis. I make the training of fatigue by Altair and tried make the analysis, but I’m not sure of the results. I think the problem it’s on the TABFAT. About the TABFAT: My analysis has 1D and 2D elements. I obtained the following values in the Linear Static Analysis: Analysis 1D Analysis 2D σ_max 24,59 MPa 267,9 Mpa σ_min -19,71 MPa 0 MPa Can I represent the load cycle of my “vehicle” like a sinusoidal curve? Can you show me how I represent it? Should I represent these values for each of the fatigue analysis like one analysis for 1D elements and other analysis for 2D elements? Can I “mix” these values for the two analyses representing σ_max = 24,59 MPa and σ_min = -19,71 MPa? I think that a correct method is consider my load cycle like a variable load, but I don’t obtain experimental data. About the MATFAT: I acquired the MATFAT data by the eFatigue website, but I don’t obtain the SE (standard error of log(N)). How I find out this? If I consider SE like “Default” (zero), how will affect my analysis? Note: I’m making a SN analysis. Thanks for helping!
2. ## Thermo-mechanical topology optimization

Hello everyone I would like to do a thermo-mechanical optimization. The thermo-mechanical analysis is already done successfully. Now I was looking for a documentation or tutorial about this sort of topology optimization, but I could not find anything. Does anybody of you have a link or documentation to share, about thermo-mechanical topology optimizations? I thank you very much in advance!
3. ## Use of dimensions in Evolve

Hey guys I'm new to solidThinking Evolve and I need help about dimensioning my drawings. Can we give dimensions to our sketches like in CATIA or solidworks? Also, can we edit position of points according to dimensions? What are dynamic and static dimensions in evolve and how are they different? Please help. Thank you in advance☺️
4. ## How to create solid bodies using loft feature?

Hello guys, I wanna know how to create solid bodies in evolve using loft feature between curves. Actually I want to create spoke of wheel rim using loft command but I'm unable to make it a solid body. Do we get solid body if we loft between all the curves? Please help me regarding this. If you have any evolve model of rim spoke that will be very appreciable. Thank you in advance
