Farouk Maaboudallah 10 Report post Posted November 7, 2019 Hi everyone, Anyone here working on the modelling of the roughness / wear on macro-scale FEM model ? Best regards, Farouk Quote Share this post Link to post Share on other sites
Rahul R 328 Report post Posted November 7, 2019 Do you want to input surface roughness for fatigue analysis?If so then you could use PFAT Bulk data entry to define same. Quote Share this post Link to post Share on other sites
Farouk Maaboudallah 10 Report post Posted November 7, 2019 The idea is to perform macro-scale contact simulation (Non linear static analysis) with smooth surface that include roughness Quote Share this post Link to post Share on other sites
Rahul R 328 Report post Posted November 8, 2019 Wear simulation is currently not possible with OptiStruct. Attached screenshot covers some highlights of OptiStruct 2019.1. Quote Share this post Link to post Share on other sites

Thanks mate for your answer Another and the last question : There is an option in OptiStruct to implement, let's say, new finite element formulation or modify the formulation of the element ... ? (like development module in Abaqus) If yes, can you please send me the documentation ? Thank you again and have a nice weekend Quote Share this post Link to post Share on other sites
