Hi All,
Can anyone advise how to use tableOnFile option of combiTable2D? It seems that there is a problem with interpreting external file content during simulation.

model lookup_test "table lookup"
  Modelica.Blocks.Sources.Ramp u1_input(height = 2, duration = 1, offset = 0, startTime = 0);
  Modelica.Blocks.Tables.CombiTable2D lookupFunction(tableOnFile = true, tableName = "table2D_1", fileName = "D:/Modelica/RailSim/Tests/lookup_test.txt");
  Modelica.Blocks.Sources.Constant u2_input(k = 2);

equation
  connect(u2_input.y,lookupFunction.u2);
  connect(u1_input.y,lookupFunction.u1);
end lookup_test;


lookup_test.txt contains the following (as in example for combiTable2D):

#1
double table2D_1(3,4)   # comment line
0.0  1.0  2.0  3.0  # u[2] grid points
1.0  1.0  3.0  5.0
2.0  2.0  4.0  6.0

double table2D_2(4,4)   # comment line
0.0  1.0  2.0  3.0  # u[2] grid points
1.0  1.0  3.0  5.0
2.0  2.0  4.0  6.0
3.0  3.0  5.0  7.0


SIMULATION RESULT:
Simulation execution failed for model: lookup_test
No table named `table2D_1' in file `D:/Modelica/RailSim/Tests/lookup_test.txt'.
Simulation terminated while the initialization. Could not find suitable initial values.

I also tried to load .mat file generated by Matlab (v4) / Dymola 2012 (demo), but no luck with simulation run. u1 and u2 are strictly monotonous in the input table, but OM gives the following message:
ISimulation execution failed for model: Model1
Table2D: independent variable u1 not strictly monotonous: 21.15 >= 0.
Simulation terminated while the initialization. Could not find suitable initial values.


In contrast, when tableOnFile=false and data specified within the model, it works fine.

Similar problem reported http://openmodelica.org/index.php/forum/topic?id=351
Any ideas what is wrong with interpreting external file?

Many thanks!
