Week - 8 - Morphing

                                  MORPHING OPERATION ON A GEOMETRY AND FE MODEL BY USING ANSA 

AIM : 

            To perform a morphing operation on a given component and FE model by using ANSA.

 OBJECTIVE :

•    To perform a morphing operation on a given geometry by using BOX morphing method.
•    To perform a morphing operation on hand rest by using BOX morphing method.

SOFTWARE USED : 

     Preprocessing software- ANSA V 22.1.1.

 MORPHING :  

•      Its one of the ANSA features which is used to change the geometry as well as FE
•      After creating FE user wants to make any change in that like creating or filling the hole, copying or moving the features , it is used to do those.

PROCEDURAL STEPS 

PROCEDURAL STEPS FOR MODEL 1

STEP 1 :   Importing the igs file of the CAD model in ANSA software by using GUI option.

                \

STEP 2 : Increase the cons resolution by using MESH > PERIMETER > LENGTH = 1mm

STEP 3: To perform TOPO to connect all surfaces in the cad model.

                                                    Without Topo 

                                                          With Topo 

STEP 4: To orient the surfaces to make sure all surfaces are in one direction.

STEP 5 :  Check the geometrical errors and cleared the geometrical errors 

              Removal of triple cons by using TOPO MODULE > CONS > RELEASE

              Then single con is converted into double cons by using TOPO MODULE > FACES > TOPO.

              The crack between the surfaces and needle face errors was fixed.

 STEP 6 : Create  PIDS for the model by using TOPO MODULE > FACES > SET PID.

STEP 7 : To perform a morphing operation on a given geometry by using BOX morphing methods.

              CLASSIC MORPH > MORPH > BOXES > NEW > ORTHO > selected the features entities need to change the geometry 

              MORPH > BOX MORPHING > MOVE > selected feature entities in which direction movement assigned by the x or y or z direction. 

                                 Before morphing in feature one                                                                                       

                      Increased the height of the feature one after morphing. 

                            Before morphing in fillet area

                              Increased the fillet size after morphing 

STEP 8 : To perform a morphing operation on a given geometry by using BOX morphing methods.

              CLASSIC MORPH > MORPH > BOXES > NEW > ORTHO > selected the features entities need to change the geometry 

              MORPH > BOX MORPHING > MOVE > selected feature nodes in which direction movement assigned by the x or y or z direction. 

                                                             Before morphing the feature 3

                                                             After morphing the feature 3

STEP 9 : To perform a morphing operation in the bolt

              CLASSIC MORPH > MORPH > BOXES > NEW > ORTHO > selected the bolt need to increase the size by scaling factors.

              MORPH > BOX MORPHING > MOVE > SCALE > SELECTED MASS COG points in the bolt and  asssigned the x=1 , y=1 , z=1 and scaling factor =10

                                                          Before morphing the bolt 

                                                After morphing the bolt

STEP 10 : MORPH > BOX MORPHING > MOVE > SCALE > asssigned the x=1 , y=1 , z=1 and scaling factor =0.10 by regaining into original position by selecting 2 nodes.

                                After translating into the original position

STEP 11 :       Stretching the fillet area before morphing 

                            After morphing the fillet area

STEP 12 : Increasing the hieght in feature4 by morphing along Y direction.

                                    Before morphing in Feature 4

                                         After morphing in Feature 4 (along X-direction)

                                          After morphing in Feature 4 (along Y-direction)

PROCEDURAL STEPS FOR MODEL 2

 STEP 1 :   Importing the igs file of the CAD model of Hand rest in ANSA software by using GUI option.

STEP 2 : Increase the cons resolution of the hand rest by using MESH > PERIMETER > LENGTH = 1mm

STEP 3:    To perform TOPO to connect all surfaces in the cad model.

STEP 4:   To orient the surfaces to make sure all surfaces are in one direction.

              Check the geometrical errors and cleared the geometrical errors 

              Removal of triple cons by using TOPO MODULE > CONS > RELEASE

              Then single con is converted into double cons by using TOPO MODULE > FACES > TOPO.

              The crack between the surfaces and needle face errors was fixed.

STEP 5 : Create  PIDS for the model by using TOPO MODULE > FACES > SET PID.

STEP 6 : To perform a morphing operation on a given hand rest geometry by using BOX morphing methods.

              CLASSIC MORPH > MORPH > BOXES > NEW > ORTHO > selected the features entities need to change the geometry 

              MORPH > BOX MORPHING > MOVE > selected feature entities ot nodes in which direction movement assigned by the x or y or z direction. 

STEP 7:                                                    Before morphing in hand rest.

                               After Morphing increaseed heights of the dog houses and ribs as per the given data (image)

 RESULT :

•   Hence two model given were successfully morphed.
•   The model-1 has been morphed according to the week-8 video, what the instructor taught.
•   The model-2 has been morphed, the circular( Dog houses ) and rectangular ribs has been increased sucessfully.

LEARNING OUTCOMES:

• In this week-8 challenge , i came to know
• How to morph the miodels.
• Learned how to create the morph box and change the shape of the model.
• Learned about various commands which are used morph the models.
