Re: How to compute output power for electric generator in altair flux?

Hi Isiaka,

You can find the output power by finding power in each conductor that belongs to a particular phase and add the power from all phases to get total power.

You can get it by plotting the PowerP(conductor) on the 2D curve.

Thank you,

Lavanya

Re: Licenses for use in university laboratories

Hi Yadira - AI Studio free version can be installed for curriculum and non-confidential research work. This does require it to be licensed to each computer though. If your university would like to arrange a network license set up for lab computers then email me at dxf@altair.com, let me know the country you are in, if for class or research and I will make sure the right academic representative contacts you.

Hey Cesar,

thanks for the tip, it sounds great! I will give it a try.

Re: Is it possible to run the voltage controlled capacitor block as a PSIM instead a SPICE model

You may use PSIM blocks to build the characteristic of a nonlinear component.

The picture below is an example. You may replace the math block with your own equations.

Re: After installation, I cannot run the PSIM program

I managed to find a solution, please confirm if it works for you.

Go to your PSIM folder (for me, C:\Altair\Altair PSIM 2022.3)
Backup psim_lic.dat or rename it to psim_lic.dat.old
Copy your provided licence file and paste in the PSIM folder
Rename it to psim_lic.dat
Run PSIM

Re: Negatif External force work

Hello,

Work is the energy transferred to or from an object via the application of force along a displacement. That means that generally work can be either positive or negative.

The work, generally, is given by the following equation:

If we simplify it for one direction this can be written as:

In this equation F must be replaced with its sign whether is positive or negative compared with the direction the body is moving. Using this equation work can be negative, for example, when the displacement is in a specific direction and the force pulls in the exact opposite.

Some other examples of negative work can be produced within models that constrain prestrain elements or non-balanced boundary conditions, even with the use of gravity. The following example examines a single element with a high initial velocity in z-axis that decelerated by gravity.

In the above model the initial velocity, and hence the displacement, are positive, while the gravity force is negative. That leads to negative work from the gravity (external force). In the following diagrams external force work and displacement of the body are given.

Re: Facing problem in defining steering lock

Hi Sudip,

These warnings are present as you have potentially exceeded some predefined values that the solver checks by default to ensure a well-defined model. Since the simulation completed and you say the simulation looks good, then I would not obsess over these warnings. If you have an atypical suspension with large allowable suspension travel, then that would be enough to trigger these warnings.

I would be extra mindful, however, of results you are extracting from the SDS reports due to these warnings. Try to do your own rough calculations to ensure these SDS values are feasible for your own peace of mind.

Hope this helps!

Re: How to connect Rapidminer with a database (ScienceDirect, Scopus etc.)?

Hi @RMNewbie,
What I use to do in this case, is to work with Scopus and export the search results with all the details that I need for my analysis as csv. After that, you can work with RM text processing extenssion to analyze your data.

best,

Cesar
