Project - 2 - Meshing on the suspension Assembly

Rear Suspension Assembly using ANSA-

Aim:-

To determine the components checks for geometrical errors and providing good mesh flow for each elements in the model by satisfying above all given criteria using surface and volume meshing with a thickness assignment from shell to solid. Additionally, below requirements also should be satisfied respectively.

• Off elements should be minimal.
• Good mesh flow
• To determine and deploying connections as per requirement throughout assembly.

Procedure:-

1. Open the ANSA software.

2. Click on the downloaded Rear suspension Assembly and open it.

3. As the model will appear. Use the command 'TOPO'(Faces>TOPO) and do window selection for all the model.

• After the TOPO cleanup, then we have to check the geometrical errors for further steps of mid-surfacing, surface and volume meshing.
• Firstly, we have to click on the 'Geometry' in the Checks manager(Tools>Checks>Geometry), then an Auto-generated template will be occured.
• Secondly, after displaying the template, likewise we have to click on the 'Execute' option in the template which will displayed the status of error visibility.

• Then, after displaying errors, we can 'auto-fix' this error. Select all the errors and by right clicking 'fix' option will be generated and by click on it auto-fix error will automatically be resolved. After, auto-fixing this error some of the errors should be fixed by our own. Thus, these errors should be resolved one after another. For this, we have to use 'Hybrid Not'(Bullens>Hybrid Not) option.
• Admittedly, these errors should be resolves sequence by sequence, so click on error and go to the option 'show only' then the error will be displayed. Likewise, go to Release(CONS>Release) option, then by clicking on it and doing window selection of TOPO in faces, our error will be resolved respectively. Similarly, we have to resolved all errors oe by one.

• Thus, when all errors are resolved, then in template it will shown geometry check status as 100% which clarify that our geometrical errors along with Topology clean up is all up to the mark.
• Therefore, our geometry is now ready for Surface and Volume meshing.

4. Our geometry is now undergo through Mid-surfacing. Basically, we preferred mid-surfacing to get a better mesh flow by converting solid to shell(2D). Additionally, we also performed surface and volume meshing for uniform and non-uniform thickness component. Likewise, we have to 'Set PID(Part ID)'(Ctrl+P) for each elements of the model. Accordingly, we have to set various color orientations for each elements in the model. After all, we have to convert these PShell PID's to PSolid i.e. volume mesh of each elements in the model. Now different elements are shown below:-

1. Chassis Frame:

1. Surface Meshing:-

• Primarily, we have preferred 'Spot'(Mesh generation>Spot) mesh option for meshing. Similarly, we have to do meshing as part by part so we need to make Project cut(Macros>Project cut) to divide the surface and likewise, we have to do the mesh as part by part.
• Before that, we need to follow some protocols, likewise primarily one of its distance between nodes at perimeter and macros. We have to measure distance and like, we have to focus on attaining same distance between nodes as well as cons. Basically, we need to assign a uniform distance, so we need to use 'Length'(Perimeters>Length) option and we have to assign target length of '4 mm' as perimeter and macros. Likewise, two protocols also we have to follow i.e. 'Number'(Perimeters>Number) and 'Slide'(Perimeters>Slide).

• For same, we have to set mentioned quality criteria as per given data. So click 'F11' a template will be generated, then we have to select required quality paramters as per assigned. Then, for same we have to click 'Presentation Parameters' in the template and we have to click on the 'elements' option and we have to show the same 'Demand effect' arrow.
• Like that, we have to click 'Mesh'(Utlities>Mesh) option and we have to set average, minimum and maximum length. Then, we have to do spot mesh one after another. Simultaneously, we have to use two commands 'Reconstruct'(Shell mesh>Reconstruct) and 'Smooth'(Shell mesh>Smooth). For reducing Off elements we have to use basically four commands namely, 'Paste'(Grids>Paste), 'Join'(Elements>Join), 'Num+/-'(Perimeters>Num +/-), 'Swap'(Elements>Swap). Thus, our element will appeared in meshing.

• As, we preferred ortho tria mesh for curved surfaces and simple tria mesh for straight or normal surface. Likewise, we have to reduce Off elements as per quality criteria for good mesh flow.
• Thus our objective is achieved. So, Chassis frame can be viewed in 'PID' mode for its colour orientation.

II. Volume Meshing:-

• After spot mesh has done on the surface, we need to define the volumes for each individual sepreately. This is done by using by 'Volume Mesh'(Volume>Define Volume>Manual) of the module.
• Then, after defining seperate volumes for each property in the module PID is set for 'Chassis Frame' by using 'Set PID'(Volume>New>PSolid) option. After attaining, PID for chassis frame, we do solid meshing for defined volume using 'Tetra Rapid'(Unstructured Mesh>Tetra Rapid) option. We prefered Tetra Rapid instead of Tetra FEM because it is more organized than Tetra FEM.
• After solid meshing, we need to check the 'Tet Collapse' named quality criteria for the solid mesh flow in Property checks manager(Quality criteria>Solids), in which it should be achieved with a value of 0.2.

• Thus, our objective is achieved. So, PSolid(Chassis Frame) can be viewed in 'PID' for its colour orientation.
