I get an "Invalid floating point operation" error when running a simulation.<br>
However, I can't find any information about the error source in the .lst file.<br>
Does anyone know if there is any method to trace at which component (and<br>

Chun Kwong,<br>
An invalid floating point error is a generic error generated by the
DLL when a problem was not caught in the code. For example, a division
by zero or sometimes taking the log of a negative number will cause an
invalid floating point error. The fortran code of the Type should
always check such arguments before executing the division or taking the
log but it doesn't always. <br>
<br>
The first thing to do is to go into the Studio control cards (where
you set the simulation time step, start time, etc.) and switch the
"debug mode" to "true." This will make your simulation run a good bit
more slowly but will check two conditions that can cause those invalid
floating points (it checks to see if an output got set to "NaN" and it
checks to make sure that no Types are writing outside of their allotted
OUT() array space. <br>
<br>
If that does not lead you to the solution and you are able to run the
simulation from the compiler in debug mode, it will sometimes stop and
indicate the line that caused the error.<br>
<br>
If neither of those solves the problem, please send me your input
file and any external files that I need in order to run it and I will
see what I can do about finding the cause of the error.<br>
<br>
Kind regards,<br>
David<br>

I would think that all you would need would be Type56 and Type109 (plus Type33 and Type69 I think). You can just set the cooling temperature in your zones to 24.2C and allow the cooling equipment to have unlimited power, then take a look at the maximum cooling load that was required. That should give you the required system size. Keep in mind three things:<br>
<br>
1. Type109 reads a typical (average) weather year file - not an extreme one and typically (right or wrong) system sizing is done based on a worst-case scenario, not on an average year.<br>
<br>
2. If you plan for your lab to have temperature setups and setbacks, your max cooling load will be enormous because technically the load is infinite when your set point temperature comes back from its set up condition. I would recommend using a constant setpoint in order to find your system size.<br>
<br>
3. The Type56 output QSENS is sensible cooling only! In order to get a latent component, you must also impose an RH setpoint on the zone and look at the QLAT output from Type56. This isn't ideal because often the latent cooling is an effect of the sensible cooling (not something that can be controlled separately). We wrote a component based on some curve fits that calculate the amount of latent cooling that a "cooling coil type" of cooling device can do based on zone temperature and ambient wet bulb (If I am remembering correctly). Its latent cooling ability turns into a negative moisture gain on the space, which is fed back to Type56. The component will be part of the TESSLibs 3.0 but for the moment is an individual component.<br>
Kind regards,<br>
David<br>

My Problem,<br>
<br>
I have 2 rooms, used as a lab.<br>
<br>
In this rooms there is a thermal load of 15kw which has to be cooled away.<br>
<br>
The ambition is the simulation of the room temperature. Target: 24°C +- 0,2 °C<br>
Question: Is the installed system strong enough, which systempower do I need?<br>
<br>
At the moment the installed system has not the ability to cool 15 kw away.<br>
<br>
is it enough to use the build (type56) and weather data(Type109) to simulate this situation?<br>
<br>
