At time 0.0 is not finite. The simulation will be stopped. There may be a singularity in the solution. If not, try reducing the step size (either by reducing the fixed step s

Hi @Chiranjeeb Das,

This is clearly a Division by zero error as shown in the Diagnostic viewer. To know which block is causing this error, go to Configuration parameters>Diagnostics>Data Validity and set Inf or NaN block outputto error and run the model.

You will get the error as follows:

An error occurred while running the simulation and the simulation was terminated.

Caused by:

• Block 'BlockName' outputs 'NaN' for element x of output port x at major time step 0

where BlockName is the block which caused this error.

After identifying the block, further debugging can be done to ensure that zero is not passed to the denominator of a division block. This helps prevent `Inf` or `NaN` values from being fed into the integrator.
