Applying Frictionless Constraint in Autodesk Simulation Mechanical

The frictionless constraint is used to resist the deformation of the selected surface in its normal direction due to the force applied on the model. You can select planar and cylindrical surfaces of a model to apply frictionless constraint by using the Frictionless tool of the Autodesk Simulation Mechanical. To apply frictionless constraint to a surface of the model, select...

Adding Parts to a Spec Sheet from a catalog in AutoCAD Plant 3D

You can add parts from a catalog to a newly created spec or an existing spec. For example, to add a pipe of size ranging from 3” to 10”, select the Pipe option from the Part category drop-down list of the Common Filters area in the Catalog Browser in AutoCAD Plant 3D, refer to the below figure. Next, you need to set the size range of the pipe to be added...

Creating Smooth Curve Between Two Existing Sketched Entities in Autodesk Inventor

In Autodesk Inventor, you can create a smooth (G2) continuous curve between two existing curves. The existing curves can be arcs, lines, splines, or projected curves. To create a smooth curve, choose the Bridge Curve tool from the Draw panel of the Sketch tab in the Ribbon of Autodesk Inventor, you will be prompted to select the curves one...

Introduction to Effective Mesh in Autodesk Simulation Mechanical

An effective mesh is a mesh that provide you maximum accuracy in less computational time. If the mesh is very fine, the result will be accurate but the time taken to obtain the result will be more. Therefore, it is very important to make proper balance between number of elements in a mesh and computational time taken for analysis. In Autodesk Simulation Mechanical, to make...

Hydrostatic Pressure in Autodesk Simulation Mechanical

Hydrostatic pressure is a pressure that is exerted by a fluid at equilibrium. It varies linearly from the level of the fluid in the direction of increasing depth of the fluid. The magnitude of the hydrostatic pressure is directly proportional to the depth of the fluid and to the density of the fluid. ...

Remote Load in Autodesk Simulation Mechanical

A remote load is a nodal load or boundary condition that is originated from a point that is located in the space, not on the model. In other words, the load that is originated from a point located in the space, transmitted to the model through line elements such as beam, truss, or similar line elements is called as remote load. You can apply a remote load like you apply...

Model Preparation using NX Nastran

Many time before analysis on a model, it is necessary to simplify that. After the simplification, the model become easy to meshing. For preparing model, we can use two type of process; geometry idealization and geometry abstraction. The geometry idealization is the process to remove or suppress features from the model for proper defining a mesh....

Creating Midsurface in NX Nastran

You can simplify your geometry for analysis by creating a midsurface. The midsurface tool generate an middle surface between pairs of surfaces selected. After generating the midsurface, you can use it to perform analysis directly and apply uniform shell meshing. Below the figure shows the master part shown with default thickness, and the next figure shows the part after...

Preparing model for Swept Meshing in NX Nastran

In Swept Meshing, the software create 2D (surface) element on one face of the model and then copy that mesh upto the target face. It then generates 3D (solid) elements connecting the two faces. In case of complex and large model, it become difficult to create swept meshing. In NX Nastran you can use Split Body tool to split the model for preparing...
