similar models don't run the same

[ladopico]

Hi, I have a model that seemed to run OK the other day. Now I have added the plot must point line and the corresponding loadcurve data, and it doesn't converge, what could be the reason?

This are the control and loadcurve parts for the model that worked:
<Control>
<time_steps>10</time_steps>
<step_size>0.0005</step_size>
<max_refs>15</max_refs>
<max_ups>10</max_ups>
<dtol>0.001</dtol>
<etol>0.01</etol>
<rtol>0</rtol>
<lstol>0.9</lstol>
<time_stepper>
<dtmin>0.00001</dtmin>
<dtmax>0.0005</dtmax>
<max_retries>20</max_retries>
<opt_iter>10</opt_iter>
</time_stepper>
</Control>
.....
<LoadData>
<loadcurve id="1" type="smooth" extend="constant">
<loadpoint>0,0</loadpoint>
<loadpoint>1,1</loadpoint>
</loadcurve>
</LoadData>

And these are those of the model that doesn't work:

<Control>
<time_steps>10</time_steps>
<step_size>0.0005</step_size>
<max_refs>15</max_refs>
<max_ups>10</max_ups>
<dtol>0.001</dtol>
<etol>0.01</etol>
<rtol>0</rtol>
<lstol>0.9</lstol>
<plot_level>PLOT_MUST_POINTS</plot_level>
<time_stepper>
<dtmin>0.00001</dtmin>
<dtmax lc="1"></dtmax>
<max_retries>20</max_retries>
<opt_iter>10</opt_iter>
</time_stepper>
</Control>


....

<LoadData>
<loadcurve id="1" type="smooth" extend="constant">
<loadpoint>0,0</loadpoint>
<loadpoint>0.0005,0.0005</loadpoint>
<loadpoint>0.001,0.0005</loadpoint>
<loadpoint>0.0015,0.0005</loadpoint>
<loadpoint>0.002,0.0005</loadpoint>
<loadpoint>0.0025,0.0005</loadpoint>
<loadpoint>0.003,0.0005</loadpoint>
<loadpoint>0.0035,0.0005</loadpoint>
<loadpoint>0.004,0.0005</loadpoint>
<loadpoint>0.0045,0.0005</loadpoint>
<loadpoint>0.005,0.0005</loadpoint>
</loadcurve>
</LoadData>

Let me know if you need the whole files, and would need to send them via email since they are very big.

Cheers.

Hi,

The only difference I see is that in the second version you should have two load curves. One for the must point, and one for the load. Could that be the problem? If you still can't get it two work, can you send me both files and I can see try to find the problem.

Cheers,

Steve.
