aim - to do 2d meshing and misd surfacing procedure - 1 try to check for any geometric erroe by executing geometric checks 2 try to show only one part at a time 3 after you select one part go to the mesh and then enter length as 1 4 then revert back to the topo menu 5 then offset 6 click on minus in bottom tool bar and…

1 First we will check the geometric clean up, there should be no errors in it. 2 Then after geometry clean up, we use middle option to create mid surface of the fins and teeth because offset option will not give perfect mid surface 3 We will take mid surface from the side where there is more grooves to get best mid surface…

I couldnt extend some surfaces because of the triple cons generated before the extend and intersection

1 FIRST STEP OF EVERY MESHING PROCESS IS TO FIRST CHECK THE GEOMETRY AND FIX ALL THE GEOMETRICAL ERRORS. 2 AFTER FIXING GEOMETRY WE DO TOPO TO ATTACH THE DESIGN FACES 3 GO TO MESH DROP DOWN AND THEN SELECT LENGTH AND THEN PERIMETER AND ENTER 1 IN THE DIALOG BOX. 4 THEN MEASURE EVERY SURFACE LENGTH IF IT IS LESS THAN MINIMUM…

done the meshing and volumetric meshing. thanks for your support

AIM:- Defining degree of freedom and motion in the rear door. PROCEDURE:- 1 we need to give different pids to all the parts which will make are connecting easier. 2 after create all the pids we need to look for single face holes and to fix it by using RBE2 option in NASTRAN module. 3 after finishing all single face hole…

Aim - To practice morphing on the component and hand rest given  Procedure- 1 first all the necessary step apply topo on the model to avoid gaps, and then go to the perimeter<length in the mesh module and enter value 1 in length 2 then shift to the morphing module and click on new option in the boxes menu and select…

aim :- to mid surface the ip console half component and do 2d meshing procedure :-1 do the topo clean up in the component 2 then go to the mesh module parameter and choose length as 1 3 off set the base surface of the component 4 mid surface all the fines by using middle in the surface tool bar 5 closed cylinders can be…

1 firstly edit and the unnecessary extra edges and toggle them to there places. 2 check if there is any yellow edges if yes then it is sign of overlapping surface so delete one surface 3 after you done withe the clean up go to the mid surface option in the geometry module. 4 then select all the surface in the in component…

aim - to get the conversion value of the given units in different measurement system 1. mass 1 kg- Kg cm ms= 1      Kg cm s= 1      gm mm ms= 10^3      kg m s = 1        g cm s = 10^3      g cm us = 10^3 g mm s= 10^3       …

AIM - To show how meshing of suspension assembly is done. PROEDURE - 1 FIRST DO THE TOPO CLEAN UP AND STITCHED AAL THE SINGLE CONS THEN GO TO THE MESH MODULE IN MESH PARAMETERS< LENGTH = 4 2 IN THE QUESTION WE ARE GIVEN 2 DIFFERENT CRITERIA FOR THE RIM AND TYRE AND FOR REST OF THE CONNECTIONS 3 SEPERATE THE RIM AND…

1 speed of sound is `sqrt (E/rho` which when is put value E =210000 and 'rho' =0.0078    c = 5188.74 2  delta tc= l/c 1000/5188.74 = 0.1927 3 0.1927sec 4 and 5  3 D MESHING 1 CHECK IF THERE IS ANY EDGE THAT NEEDS TO BE TOGGLED OR IS CREATING ANY SINGLE CONS, IF NOT THEN NEXT STEP IS THAT AS THERE…

Aim- to study the change in energy when we change the shell properties and analyse the difference 1 import the starter file in hyperworks 2 to change the Tstop we need to go to cards and click on eng_run, and change Tstop from 60 to 55. 3 in second question we have to change the animation steps which means we ahve to change…

CASE 1 1 IMPORT THE FAILURE JOHNSON FILE WHICH HAS 0000.RAD IN THE ENDING, 2 THEN AFTER IMPORTING THE FILE CLICK ON ANALYSIS THEN RADIO, MAKE A NEW FOLDER OF CASE 1, AND IN THE RADIOS OPERATION NAME THE RADIOS FILE AS LAW2_EPSMAX_FAILURE_0000.RAD 3 AFTER CLICKING ON RADIOS A BOX WILL APPEAR WHICH WILL GENERATE THE SOLUTION…

Explicit methods calculate the state of a system at a later time from the state of the system at the current time, while implicit methods find a solution by solving an equation involving both the current state of the system and the later one. Mathematically, if {\displaystyle Y(t)} is the current…

AIM- To see the difference in forces when different boundary conditions are apply/ any change on the body is done. procedure- 1 open the bumper system file in hyper mesh, and select radios and ok 2 then first go to surface edit and trim with surf/ plane select every surface and use trim. 3 to attach the different surfaces…

aim - to set up the given simulation conditions on the model for frontal crash simulation in hypermesh/radioss and discuss the result observed procedure first check the unit system used it should be kg mm ms, you can see it by open starter file in notepad then import the starter file in hypercrash now check for any penetration…

Aim- To study the deformation causes by a side pole when a car hits the pole sideways, studing the forces and energy graph to see the changes Procedure- 1 import the model in hyperworks and check the units in use 2 the open this file in hypercrash to check penetration and add mass and velocity check all solver contact…

AIM- To perform drop test of cell phone using ls dyna solver and give detailed report procedure open the keyword file which was given in the question the file consists of a mobile phone model and a rigis wall solid element and shell element i this we are going to delete the solid wall element because the solid element…

aim- crash analysis of a box havng two different thickness 1.2 and 1.5 and study the changes in the energy or forces thru graphs procedure- open the keyword file provided in the question in ls dyna software and see the keyword manager now we need to create section properties KEYWORD MANAGER> SECTION> SHELL Now we…

Aim - To model spot welds for the assembly and simulate crash test analysis for the given Procedure - open the k file in ls prepost check all the keywords in the model then lets start with renaming the parts in the model by top and bottom now to connect we need to ontroduce spot weld in between the top and the bottom of…
