Hi,
You shouldn't need to install anything else. The installation should work without any problem. You should uninstall any old installation first. Any error messages? What Windows do you have? To help me point out where the problem might be can you run from command line: msiexec /i "C:\path\to\OM.msi" /L*v "omlog.txt" OM=OpenModelica-NIGTHLY-BUILD...msi then zip and send me directly the omlog.txt file.

Dear Adrian, i just tried to install openmodelica, but the installation failed. Do i need to install another program to use openmodelica? Thanks a lot Zakia/IFP -----Message d'origine----- De : [email protected] [mailto:[email protected]]de la part de Adrian Pop Envoyé : vendredi 12 décembre 2008 04:46 À : [email protected] Objet : Re: Problem with OpenModelica simulation Hi, There is a new nightly-build available here: http://www.ida.liu.se/~pelab/modelica/OpenModelica/OMC/nightly-builds/ which should (hopefully :) deal with your problem. Cheers, Adrian Pop/ Pranesh Rao wrote:I found the problem in my simulation. I had to add a small capacitor between the anode of diode D6 and ground g. The model works in Dymola but still not in OpenModelica because of the data structure problem that Adrian pointed out. Thanks.

I will look at the model and see what I am missing - perhaps a decoupling capacitor or something. Again, thanks.

They should actually be dynamic, but that's another story. I'll generate a new nightly-build in a couple of days and let you know when is available.The generated system of equations seems to be singular so you might also need to do some changes in your model. Maybe some other people on the list can help you with that.Cheers, Adrian Pop/ Pranesh Rao wrote:Hi, I am trying to simulate the following model using OpenModelica 1.4.4 and the Modelica 3.0 library:model br3ph1 "three phase diode bridge feeding R-L load (source inductance present)"constant Real PI = Modelica.Constants.pi;Modelica.Electrical.Analog.Sources.SineVoltage src_a(V=120.0,phase=0,freqHz=60.0);Modelica.Electrical.Analog.Sources.SineVoltage src_b(V=120.0,phase=-2*PI/3,freqHz=60.0);Modelica.Electrical.Analog.Sources.SineVoltage src_c(V=120.0,phase=2*PI/3,freqHz=60.0);Modelica.Electrical.Analog.Basic.Resistor rs[3](each R=0.1) "source resistance"; Modelica.Electrical.Analog.Basic.Inductor ls[3](each L=1e-3) "source inductance"; Modelica.Electrical.Analog.Ideal.IdealDiode D1,D2,D3,D4,D5,D6; Modelica.Electrical.Analog.Basic.Resistor r_l(R=1) "load resistance"; Modelica.Electrical.Analog.Basic.Inductor l_l(L=0.1) "load inductance"; Modelica.Electrical.Analog.Basic.Ground g; Real v_out, i_out; equation connect(src_a.p,rs[1].p); connect(src_b.p,rs[2].p); connect(src_c.p,rs[3].p); connect(src_a.n,src_b.n); connect(src_b.n,src_c.n); connect(src_c.n,g.p); connect(rs[1].n,ls[1].p); connect(rs[2].n,ls[2].p); connect(rs[3].n,ls[3].p); connect(ls[1].n,D1.p); connect(D1.p,D4.n); connect(ls[2].n,D3.p); connect(D3.p,D6.n); connect(ls[3].n,D5.p); connect(D5.p,D2.n); connect(D1.n,D3.n); connect(D3.n,D5.n); connect(D5.n,r_l.p); connect(r_l.n,l_l.p); connect(l_l.n,D2.p); connect(D2.p,D6.p); connect(D6.p,D4.p); v_out = r_l.p.v - l_l.n.v; i_out = r_l.p.i; end br3ph1; When I run it using simulate(br3ph1,stopTime=1.0, numberOfIntervals=5000) I get a Simulation failed message.

Please contact the application's support team for more information. I am new to Modelica so this could well be operator error. Any help would be much appreciated. Regards, Pranesh Rao
