Assignment 2-RADIOSS Engine File Editing & 3D Meshing Challenge

REPORT

AIM:- To Perform 3D Meshing ,and setting up 1D elements on the panels and to Run the Radioss file by editing the required values .

What Will I learn? :- This makes sure that we get a thorough approach towards 3D meshing and 1D elemnts for FEA in Hypermesh also running a radioss file would drive through various solvers of Hypermesh.

Three (3) different procedures have been stated here separately

3D MESHING PROCEDURE:-

1. To Start 3D meshing its essential that geometry has to be automeshed under 2D meshing with mesh size as 10 and mesh is performed
2. After 2D meshing is performed we choose few options from 3D meshing such as to create hexa elements and we prefer the options of setting elemnts as trias or quads.
3. Also we can perform in bulit 3D meshing using mesh and it can be directky generated where in few elemnts are automatically cleared up and mesh is performed.
4. For Arm Bracket since there are various elements individually each element has been meshed using 2D auto mesh then 3D mesh has been performed.
5. For curved elements spin feature has been used to create the mesh on the elements .
6. For Boss element circular face has been extracted and mesh was performed by clicking onto nodes and making a viable selction.

1D ELEMENTS PROCEDURE:-

1. To Align elements firstly 2D Automesh has to be performed on both the surfaces with same number of nodes on both plates.
2. If A non surface is present and to make it into surface click on surface generation and use spline feature
3. Now nodes of Both the plated have to be matched so inorder to do that click on the nodes on first surface and align with the node on other surface.
4. To do this use features such as bar which generates truss ,and rods generates beam and spring feature.
5. To do the welding procedure click onto the 1D edit and connectors and use spot feature so to generate welds.
6. Also using seam weld would generate same way of nodes and connectivity around the feature and these connectors can be exported to rad files and also to hm file format.

RADIOSS PROCEDURE:-

1. To run a radioss file firstly input the radioss file with default hypermesh software kept as radioss.
2. Here it gives the provision of providing the frequency values that were required to be edited
3. Since the default time run shows 60s and requied steps are 20 we enter frequency of 60/20 i.e =3 such that file would be generated.
4. After giving the values in ENG DATA we need to Run it such as to generate the reuired steps .

CONCLUSION:-

Performing the steps as per the procedure specified for three 3 different methods we achieved the results of 3D meshing,1D elements and running Radioss Respectively these have achieved the desired values and preferable mesh.

INFERENCES:-

This has given us hands o experience over the Hypermesh Software over various features such as 3D meshing 1D elements and radioss by applying different tools.
