Week 4-1D Element Creation Challenge

Aim: To Create 1D elements and Create a Mesh on mid of the component

Objective: Meshing on the mid surface of the component and creating 1D element by assigning property to each element

Procedure: The component was IGS component so it was imported to HM

Step 1:The Mid was extracted from the component and was assigned property 

                                   

                                    Fig 1:Mid of the component

Step 2:further the material was assigned to the brackets with definite property

                            

           Fig : Property card for the model                 Fig: Material Card 

Step 3: After this washer splits were introduced at the circles for attaining proper mesh flow at edges of circles

Step 4: Then further the model was meshed with given element size of 5 units.

                                                 

                                        Fig: Meshed model along with 1D rigid elements

Step 5: For the rigid element cretaion 1D tab was used and  Dof's were given to the respective element as per above criteria 

Step 6: Then after this Beam,bar and rod elements were cretaed with given cross section in hyperbeam and optistruct tab

                            

Fig : I section (Beam)                        Fig: Cross section (Bar)                       Fig : Box section(Rod)

Step 7: Then futher this cross section rod,beam,bar elements were connected to the  RBE2 and RBE3 Master nodes 

                                                       

                                                       Fig: Hyperbeam connections .

Step 8: Further mass was loaded on the RBE2 element of given magnitude 10(CONMI1)

Step 9: For CELAS elements springs tab in 1D was used and cretaed at the master nodes of RBE2

                                                           

                                                                 Fig: CELAS 1 Element 

Step 9: Finally the challenge was completed and property wise view was taken for confirmation of element creation and connection

                                            

                                       Fig : property wise view of final model.

Conclusion: Hence the mesh was cretaed on the mid and properety was assigned allong with 1D element creation

Learning Outcomes: Learned how to extract mid and assigning property to the component along with 1D element creation and connection and how to update the DOF and property of the 1D elements also came to know how to create CELAS elements and how to assign mass on the model
