Solution of question 1:-   to change the run time first imported the solver deck into HyperMesh (0.rad file/ starter file) then I clicked on the "cards" of the model in the model browser then I selected the Eng_Run property then a drop-down appeared where I changed the "Tstop" from 60 to 50ms as mentioned in the question…

Solution of Question 1:-   So to check the material properties of the rail component we have to open the 0.rad file  because as we know that all the details and information related to material, initial loads, mesh, the unit system used, etc about the model is stored in the 0.rad file Which is also called the…

Objective:- We have to create a mesh for the given Modal "Plastic Bottle cap" for which we have to look for geometrical errors first before performing any operation on it then we have to create a mid surface out of the cap if the geometry has non-uniform thickness then we have to use manual methods for extracting mid surface…

Objective:- our main objective in this modal is to create a mesh for that, we need to create a 2d mid surface of the given modal because as we will be doing the 2d mesh before and after creating the mesh by using appropriate tools we need to do geometry clean up  so that we get a perfect surface and as a result a…

Situation:- Here the situation is that we got a Modal in (.hm) format of an inner side door of a car so we imported the modal using the import modal option in the Altair Hyperworks this side door is basically made of plastic and it has a lot of uneven surfaces and sections this is basically inside part of a car door it…

Situation:- Here the situation is that we got a Modal in (.hm) format of a rear-wheel holder of a car so we imported the modal using import modal option in the Altair Hyperworks A rear wheel is mostly situated at the backside of the car or say on the back door of a car the rear wheel holder is used for holding a spare…
