NX 8 CAE

It is a useful software in mechanical engineering

Avantages :

The software allows modeling, simulation and design for many topics in mechanical engineering and others fileds

Inconvénients :

It is an expensive software, the technical support is late. This require a previous knowledge for use it.

Siemens NX8 is a great way to analyze NX CAD models or assemblies for stress and deflection

Commentaires : Using NX8 CAE allowed me to load and constrain CAD models and assemblies, to know how much stress and deflection the designs were seeing. The Mesher is quick and there many options. Manually defining welds with connector meshes is actually efficient because everything is known and defined by the user, whereas auto weld/connectors may overconstrain a part and produce inaccurate results. Correlation between real-world failures and NX8 CAE was good, so there was confidence in the designs released. It is very thorough, capable software, but the price tag is high and Siemens have to realize that companies like SimSolid are producing equally capable software, for similar applications, at a fraction of the price, hence recommending is about neutral.

Avantages :

NX8 CAE is structured with three files: your Idealized Part, your FEM , and your SIM. The idealized part is nice because it is linked to your CAD part, but it's just a representation of it. You can tune it and remove features without affecting your original part. The FEM contains the mesh, and the SIM contains the loads and constraints. Not all analysis software compartmentalizes everything this way, but I think it's a good job and keeps things organized, which not all software does. Meshing is quite quick compared to other software. Before NX CAE, I was an I-DEAS FEA user, and find it much more modern than that.

Inconvénients :

SIM file run times can be a bit slow at times. If a run fails, not much information is given, and you have to sift through a long, cumbersome results file. Establishing contact definition between parts is cumbersome. The graphics and selection functions for loads and constraints could do with better graphics for added clarity.

NX CAE Review

Avantages :

The ting i most like about the software is the capability to have the chance to model, design and simulate 3D parts. Overall is a good software.

Inconvénients :

Compared to other softwares, the CAE aspect is a little bit weak, p.e. the mesh option is not the fastest on the market, neither the one who offers a simple interface.

Its a CAD workhorse

Commentaires : I use NX 8 to do all of my 3D modelling and engineering drawings. Most items are simple enough to figure out. Its is very order specific on its operations which can be frustrating for some, but I feel it gives me more control to the thinking rather than letting the computer assume it knows what I want. There are more options available for modelling than other softwares and the layering feature really helps me keep my models and drawings clean.

Avantages :

This software is able to do most anything that I want it to do. It can handle simple modelling of single components all the way through complex moving assemblies. It especially seems to excel at surface modelling like articular surfaces of joint replacements.

Inconvénients :

Some of its features like flows and sweeps are frustrating to learn and use. Operations are very order specific (which I like on other features) but the directions are fairly vague and aren't intuitive to figure out.

A good CAD software tool for modeling and assembly.

Commentaires : Modelling and assemblies through CAD software tool made easy.

Avantages :

In model tab we can preset the dimension according to our standard which will followed through out the modeling process. In sketching after completion of sketch, user can constrain the line as per user convenient which helps in alter in dimension if user need to change dimension. In drafting from 3D model to 2D model user are allowed to choose different views of the model and selection of different size of sheets is helpful.

Inconvénients :

User interface is need improve the accessible of tools easily. NX 8 CAE is bit bulk software for lower end laptop and PC. It should not allow user to continue the modelling or assembly process if there is an error in design process.
