Comparison of Methods for Computing Cooling Tower Demand Curves.pdf NumericalIntegration.zip

]]>I 've tried a lot of different formulations and settings when trying to output a request file from and ADAMS model, but none of them managed to keep a completely steady output step. What I mean is that even thought I request an output about every 9e-5 seconds (10240 Hz sampling frequency), at some steps, the output time in the request file is larger, about 1e-4 seconds. Is there a way to guarantee an exact output step?

Thanks in advance!

Boundary similarity and source/destination incompatibility

Where source and destination are defined - not sure what it means?

This is where "Boundary similarity: src2dst_bp3_cp1_sim5" are defined. I have selected it in the model to the right.

Anyone more experienced than me who might have an idea of whats going on?

I am currently a freshman CS major and am having difficulty understanding how what I’m learning (things like data structures and algorithms) apply to what would be expected of me when I get a SWE internship or job.

I can’t imagine that the job is just doing leet code style problems. I’m scared that once I get a SWE position, I won’t be able to do anything because I don’t know how to apply these skills.

I think it would really help if you guys could provide some examples of what software engineers do on a day to day basis and how the conceptual things learned in college are used to build applications.

could you tell me which are the most famous and useful FEM programs used to designing boiler and pressure vessels??

Thanks in advance

Applications:

Friction Losses calculations of piping network.

Irrigation piping.

Fire sprinklers system.

Water mist fire piping.

Domestic water pump estimation.

It is equipped with database engine.

You can store, edit and retrieve your data anytime.

You can Print reports.

It can transform your calculations to drawing and export it to AutoCAD.

It can export your calculations to Excel.

It equipped also with Lite CAD software.

It is equipped also with unit convertor software.

Hi everyone,

I am working with abaqus by using XFEM.

I am modelling a Single Lap Joint and I have simulated the crack propagation within the adhesive. Nonetheless, I also want to extract the Load-Displacement curves from my simulation model. The thing is, wen I plot them, I get extremelly high values, which are not correct as well as the curve does not show that a crack has been initiated and propagated by having a decrease in the load.

If someone has been through the same problem as I, or has the knowledge of simulating XFEM in Abaqus, please help me!

Thank you in advance :)

Im keen to learn as musch as I can about CFD and would like to start with Flow simulation using solidworks. Does anyone know of any free resources for education on this software ebooks, tutorials books or even CFD using flow simulation. I have an existing conjugage heat transfer project and I m trying to learn how I set up the system for analysis using the software.

I am just a beginner wanting to learn this field.

Thx for any help.

EES is a powerful tool forsolving engineering problems and is relatively easy to learn. It isparticularly useful in solving thermodynamic and heat transfer problems sinceit offers several built-in libraries comprising of thermodynamic andthermophysical properties, hence there is no need to look these values up intables. Moreover, algebraic mistakes are not a concern and the use of EES istime efficient in solving complicated engineering problems. One major advantageto EES is that it can solve a system of simultaneous equations, which is noteasy to do using Excel. This includes a system with a transcendental equation(i.e. one in which the dependent variable cannot be isolated).

This introduction is to help youget started with EES. If additional help is required, you can refer to the *Help Window* within the software or the *PDF manual* available on line. To aide inyour introduction of the software an example problem from your textbook (Moranand Shapiro) is solved using EES. The solution of the problem and descriptionof specific functions in EES are based on the PC version of EES, however thereis little difference in the Mac version. There are additional example problemslisted under the Examples menu in EES. When you are working on your homeworksets, it may be useful to search for similar problems in this menu.

Respected sir,

I am a student of mechanical engineering second year and I want to pursue my career in designing.

In first year I completed my Autocad course. But now i want to do more high level work in designing, so for this reason i want your precious suggestion on

**which software to do solid works, catia or pro-e.**

**and also difference between them, and which one will be more required.**

**I am looking forward for your reply .**

**thanking you sir.**

U might be knowing only few. names

and so this thread has been created.....

If u know one name and me another , and we exchange we will be knowing abt two softwares.....

Please Use

Post Reply to Add Software name

Also write what it deals with .... What r its capabilities...Specialization ...and more u know abt it...

Hardware requirements!!!!

Whose Developer : Company name

Email to friend to email this topic to all Mechanical Engineers You know.....so that we can have great list here....

Looking forward for great list....

I'm having a problem to calculate the efficiency inside a specific domain.

Lets suppose i have a 2D duct with a burglary and i want to see how the Strain Rate behaves through this duct. I want to calculate the efficiency of the Strain Rate inside that burglary domain, like in the picture attached.

Can someone help me ?
