week 4

Aim :- Create a 1D element with specified cross section & DOF.

Steps :- Intially open the hpermesh window

The user profile on which we have to work is optistruct.

Next is to extract the geometry on which the work needs to be done.

Then geometry is imported.

Procedure :-

Mid surface:

- The given geometry is extracted.

- For the given model the mid surface needs to be extracted.

- Then further action needs to be carried out.

- The mid surface is extracted seperately for each brackets.

Material specification and property:

- The material needs to be specified.

- We are assigning steel has material for the given brackets.

- Then the properties needs to be assignedseperately by right mouse clicking & it is renamed.

Meshing:

- Then mesh needs to bbe created.

- by going to 2d option and selecting automesh is bieng creted for the mid surface.

Hyperbeam view

- Initially a rod is created under specified condition.

- Then a beam (I section ) is created under specific condition.

- Then a bar element is created under specifi condition

Creating 1D element:

- The 1D option is selected.

- Totally 3 elements need to created using different links & different DOF.

Rod element

- The rod element is created using RBE 2 link.

- The rod element is created with only 3 DOF switching of the rotational DOF.

- Then the element is specified with an property.

- then condition is updated to the elements.

Beam element

- The beam (I section ) element is created with all DOF.

- The beam element is specified with an property.

- The beam element is created eith all DOF.

- Then the condition is updated to the elements.

Bar element

- The bar element is created using RBE 3 link.

- The rod element is createed with only x and y DOF.

- Then the element is specified with and property.

- then the condition is updated to the element.

conclusion :

The element are cleaned up and meshed and uploaded with specific needs and requirements listed, the agenda of the challenge is to analys the clean up tools and to get practised with 1D element tools and to use different type of links and their specifications.
