WIO - INPUTOUTPUT

The current free disk storage space is less than the estimated amount for all output data. The simulation will stop once the disk is full.

The solver estimates the required storage based on the file size of the initial output. This value may or may not represent the final storage requirements as the number of particles may change during the simulation.

There are seven columns in the provided input file. Ignoring velocity data as inputfileReadMode is set to INPTFL_PXYZ.

The solver issues this warning when it detects a seven-column (phase, x, y, z, u, v, w) input file and the read option is set to "INPTFL_PXYZ". In this case the velocity data are ignored and the simulation continues normally. Please specify the read option of "INPTFL_PXYZUVW" if reading of input velocity data are required.

There are four columns in the provided input file. Switching the inputfileReadMode to INPTFL_PXYZ.

When the solver detects a four-column (phase, x, y, z) input file when a read option of "INPTFL_PXYZUVW" is requested, it switches the input file mode to four-column "INPTFL_PXYZ" and issues this warning. This warning may point to an issue with the input file (incorrect path or export), otherwise the simulation will proceed normally.

Case directory exists but content does not match the current target, assuming distributed file system topology.

This warning indicates that the solver has encountered a similarly named case directory on a multinode run during file system topology identification, however, the information within the directory does not belong to the current run. This may be an artifact of a previously failed run and the simulation may continue normally, assuming a distributed file system topology. Please specify the file system topology explicitly through the cfg file if the automatically detected one is incorrect.

No STL file specified for phase #1 (S1).

No STL file has been specified in "stl" keyword of "phase" subsection under "phases" section.

Cannot find STL file S1 for phase #1 (S2).

The solver is not able to find STL file specified in "stl" keyword of "phase" subsection under "phases" section. Please make sure the file exists and/or the path to the file in cfg is correct.

At least one output time from the particle output times file has been ignored

The output times in the particle output times file from "t_output_file" in "simulationParameters" have to be monotonically increasing. If one time value is bigger than the previous one, it will be ignored. Also, time values smaller than the start (simulation) time of the run will be ignored, which can be the desired behavior when reusing a file across a restart. Please make sure the particle output times provided in the file are correct. This warning is only displayed once, regardless of the number of ignored times.

At least one output time from the restart output times file has been ignored

The output times in the restart output times file from "t_output_restart_file" in "simulationParameters" have to be monotonically increasing. If one time value is bigger than the previous one, it will be ignored. Also, time values smaller than the start (simulation) time of the run will be ignored, which can be the desired behavior when reusing a file across a restart. Please make sure the restart output times provided in the file are correct. This warning is only displayed once, regardless of the number of ignored times.

At least one particle has a phase ID smaller than one.

Smallest acceptable phase number is 1. Any particle with a phase number smaller than 1 is ignored.

At least one particle has a phase ID greater than the total number of phases.

Largest acceptable phase number is equal to the maximum number of phases defined in the cfg. Any particle with a larger phase number is ignored.

The input discretized geometry file contains #1 out-of-domain particles. Please refer to "outofdomain.txt" file for further information.

Any particle residing outside of the cuboid defined by "min_domain" and "max_domain" is ignored. If "min_domain" and "max_domain" were not defined, "min_boundingbox" and "max_boundingbox" values are used to define the cuboid. Phase and coordinates of the ignored particles are written to "outofdomain.txt".

The maximum magnitude of WALL/MOVINGWALL normals is #1. A simulation with maximum normal magnitude larger than 1.1 may behave unexpectedly.

A large normal magnitude may result in fluid particle loss and/or unexpected errors. A large normal magnitude points to flaws in descretized geometry such as separated WALL/MOVINGWALL particles or unresolved features.

All particles of MOVINGWALL phase #1 have left the domain. The simulation may behave unexpectedly.

This warning is shown when no MOVINGWALL particles of a certain phase are present at the start of a simulation. This may or may not lead to an issue during the simulation.

All particles of phase #1 have left the domain. The simulation may behave unexpectedly.

This warning is shown when particles of a certain WALL/MOVINGWALL phase are no longer present in the computational domain. This may or may not lead to an issue during the simulation.

There are #1 particles in the domain that have neighbors closer than 0.9dx in distance. Please refer to "overlapping.txt" file for further information.

While having overlapping particles does not necessarily lead to a failing simulation, it may point to certain flaws in solver input. One common flaw is the presence of duplicate particles in the discretized geometry. Another reason may be wrong "dx" or "inputfile_factor" in the cfg file.
