Hi Peter

Comment out the contents of the setstatusbar function in the installdynasys file. Otherwise look at the Getting Started pdf to see how to install the toolbox manually.

Regards

Hi Peter

You will have to recompile for the MAC. I have not tried this before on a MAC so unfortunately I cannot say if it will work or not.

Hi Alexander

I am not sure what the problem is, but you could also just copy the files and make sure the paths are correct. See the "Getting Started" pdf. It explains where to copy the files, as well as the path definition that is needed. I will see if I can find out what is going on.

Hi Arne

I have not tried this before, although we have done something similar with ADAMS. In ADAMS there is a setting where you can either use ADAMS for the derivative calculation or Simulink. The option needs to be set to Simulink. Maybe VLM has something similar. I cannot even offer to try and debug this because we do not have a VLM license.

You may also want to check the size of your model, compared to the size defined in Ndim. We had problems before when Ndim becomes larger than 100, and we still do not really know why.

Another option may be to construct a reduced order model from the VLM model. You can for instance see if you can use Eureqa or similar tools on a time history of your model, and see if you can get some ODE's from this. You will need to provide enough information though.

Another option may be to try and generate C-code from VLM, and see if you can link this in to vanilla AUTO.

Unfortunately the new version is not available yet. We are currently trying to generate a TLC script that will generate c-code from a Simulink model and link this in to AUTO. This is tricky and I have not had a lot of time to work on this.

Hi Arne

I am on holiday until the new year. I will try to look at it then. We are also working on a newer version of the toolbox, so we may update the toolbox as well in the new year. We are trying to add some new features where you can run Simulink Coder code to make the runs faster.

Hi Etienne,
I re-downloaded the toolbox, and when I run

installdynasys

in the MATLAB command line, I get the following errors:

No appropriate method, property, or field fFigureClient for class
com.mathworks.hg.peer.HG1FigurePeer.

Error in installdynasys>setstatusbar (line 369)
jRootPane = jFrame.fFigureClient.getWindow;

Error in installdynasys>installpb_Callback (line 316)
setstatusbar(gcf,'');

Error in gui_mainfcn (line 96)
feval(varargin{:});

Error in installdynasys (line 63)
gui_mainfcn(gui_State, varargin{:});

Error in
guidemfile/@(hObject,eventdata)installdynasys('installpb_Callback',hObject,eventdata,guidata(hObject))


Error while evaluating uicontrol Callback.

I am utterly clueless what this is.
Regards,
Peter

Forgot to mention the Matlab version is R2012b.
