"Floating Point overflow saving to time 0.000000"

I am getting this error when allocating resources using allocation by priority function. Can anyone give insights about this error?.

Thanks
Krishna

Can you paste the full error, or post the model?

FYI I have made a couple of independent models and then have copied and pasted each of these models in a single model (which I call the assembled model). I don't get this error when I run the models separately, but when I run the assembled model I get this error.

Thanks

Can you post the model? Or check the equation for "design resources allocation to phases stage 1 cds" to make sure there is not a divide by zero.

Tony.

More generally, your strategy should be to trace this inputs to "design resources allocation to phases stage 1 cds[concept]" which the output window indicates as the source of the problem. The table tool is generally good for that. - Tom

Chapter 7 of the User's Guide shows the process for tracing down floating point errors.

Hi all,

Thanks for the information. I have been trying to troubleshoot the error but have no clue of ts origin. FYI i have copied different independently working models to a single model. When run independently all the models are simulating with no errors and sensible results. But the assembled model is producing errors. I am uploading the model for you.

Thanks
Krishna

I am unable to upload the model it says the file is too big. FYI The size of the file 350KB. For your information I am upload the screen shot of the table view of the variable.

Email the model if you want (tony@ventanasystems.co.uk).

Tony.

If you use the table tool and work backwards, the problem is easily found.

Some of the parameters used by the allocate function (eg, ALLOCATION PRIORITY CDS) are missing values. Fill these in and it should all be ok.
