how to start ??

[tziolek]

Hello Guys,

I just discovered this whole PYmapdl and think it is really great but cannot get my head around it...

I have Ansys 2021R2 installed and was just starting with Python scripting there.

Now I have installed ansys-api-mapdl-v0 0.4.1 somehow via cmd command; have Python 3.9 installed and got the Visual Studio Code but I'm really getting lost here ... not exactly sure about the functionalities

is there anybody that could help me out here to set it up so that it works? I'm not really a programmer, more structural engineer that would like to learn :) perhaps somebody willing to have some session online ?

Thanks Tomasz

ansys-api-mapdl-v0 0.4.1

I think thats not the one you want. You should have a look at Getting Started. What you need is most likly: pip install ansys-mapdl-core

I think thats not the one you want. You should have a look at Getting Started. What you need is most likly: pip install ansys-mapdl-core

Exactly. More or less the steps are:

1. Install Ansys
2. Install Python
3. Install ansys-mapdl-core
4. Create a python file and write something like:

   from ansys.mapdl.core import launch_mapdl
   mapdl = launch_mapdl()
   print(mapdl)

   This will launch a mapdl session and connect to it. Then you can write more commands to things. You can have a look at the examples:

   • https://dev.mapdldocs.pyansys.com/user_guide/extended_examples/ex_01-gmsh_example/ex_01-gmsh_example.html
   • https://dev.mapdldocs.pyansys.com/user_guide/extended_examples/techdemo-1/ex_0-tecbrakesqueal.html

These are part of the dev.madpldocs.pyansys.com which is the development documentation, which means it is not perfect but it will give you a taste. We are working on improving them more and more.

Thanks guys - followed the steps looks something is not working; is this only valid for Mechanical Enterprise ? I have Ansys Mechancial Pro license

[germa89]

There are two possible solutions to this:

• Adding license_type='pro' or license_type='mech_1' option to the launcher. This was implemented in lastest versions, so you might not be able to use it if you have 0.6 or lower.
• Adding additional switches, additional_switches="-p mech_1". This is an additional string it is added to the command line when you start the MAPDL session. The -p flag stands for product and the mech_1 is your type of license ('Ansys Mechanical Pro')

I hope it helps!

Hi Germa

thanks for additional lines but still same issue

I did add in python license_type='pro' license_type='mech_1' additional_switches="-p mech_1"

before executing each time

from ansys.mapdl.core import launch_mapdl mapdl = launch_mapdl()

Still problem

I have an Ansys license dedicated to my PC; its not a floating license - is that something relevant?

anything else I can try ?

[germa89]

I think you are half way there. Try:

from ansys.mapdl.core import launch_mapdl
mapdl = launch_mapdl(license_type='mech_1')

or

from ansys.mapdl.core import launch_mapdl
mapdl = launch_mapdl(additional_switches="-p mech_1")

[tziolek]

YES!!!! now its working but I have no clue what to do next actually :)

super thanks - its quite some crazy stuff you guys are doing; hope to learn a lot coming days

[germa89]

I'm happy it works for you!

To start, you can have a look to the example library: https://mapdldocs.pyansys.com/examples/index.html

I'm closing the issue then.
