# Errors

Each error consists of the Error Code, Error Message and Description. A typical error message might look like:
EXX## Keyword §1 and number #1, option §2 and id #2, §1 clashes with #2
This means strings §1 and §2 are incorrect and numbers #1 and #2 are incompatible. Changing §1 and #2 may resolve this issue.
Important: This glossary is only valid for nanoFluidX 2022.2. The codes and messages may not match other versions.

## Error Code

When an error occurs, nanoFluidX will issue a corresponding code for that error. An error code starts with the letter E followed by a two-letter category identifier. For example, IO for input/output. The last element of the error code is a number representing the order within the category. For example, EIO 338.

Tip: Use this code to find the description in the glossary. Avoid searching for the error message issued by the solver as these messages have runtime generated parts which are not reflected in the glossary.
Note: The severity of an issue and its error/warning code have no relationship.

## Error Message

This is the message issued by nanoFluidX in case of an error. The runtime elements are replaced with numbered symbols.
• §: This symbol represents a string such as a phase name or file path. These symbols are followed by a number according to their order in the message. A recurring § symbol will keep the same number.
• #: This symbol represents a number such as a phase ID or motion ID. These symbols are followed by a number according to their order in the message. A recurring # symbol will keep the same number.

## Error Description

This is an interpretation of the solver message. It may involve further explanation on why a certain situation occurs, the reason why the message has been issued, or the steps to take to alleviate the problem. It is meant as a first point of reference when a question on a certain message arises.

## ECM - CELLMESH

### ECM1

Cell number exceeds value range representable by ID type.
There are more cells in the computational domain than supported by the solver. Among others, this may be due to incorrect or incompatible input file export, min/max_domain, min/max_boundingbox, inputfile_factor, dx, r_c_dx or cutoff. In rare situations this error means the case is larger than what the solver supports.

### ECM2

Resource limit in #1, #2 (#3,#4,#5) at (#6,#7,#8) in #9
This error suggests that considerable number of particles are concentrated in a certain region of the computational domain positioned about (#6,#7,#8). This error does not point to a specific cause for particle concentration and one should revisit the inputs to the solver. Among different reasons for this error are:
• particles clumping due to compression between moving walls
• too large of a timestep size
• too large of a single phase surface tension coefficient
• incorrect motion definitions
• unusual motion combinations
• kernel dx in cfg doesn't match the actual dx in the discretized geometry
• discretized geometric irregularities
• hanging or overlapping particles

### ECM3

Resource limit in #1, #2 (#3,#4,#5) at (#6,#7,#8) in #9
Refer to previous description.

## EDM - DOMAIN

### EDM1

There are no motions, inlet regions or imposed regions to deduce a reference velocity. Please provide an explicit ref_vel in domain parameters section of the configuration file.
At least one motion, inlet region or imposed region definition is required to calculate the reference velocity "ref_vel" through fallback method. Providing an explicit reference velocity "ref_vel" would circumvent this error.

### EDM2

The reference velocity "ref_vel" must be explicitly defined when a POSITION_FILE motion is present.
The solver has no fallback method for calculating the reference velocity of a "POSITION_FILE" type motion. Please provide a value for "ref_vel" keyword in "domain" section explicitly to recover from this error.

### EDM3

The solver has no fallback method for calculating the reference velocity of a "PASSIVE_RIGID_BODY" type motion. Please provide a value for "ref_vel" keyword in "domain" section explicitly to recover from this error.

### EDM4

Reference length "ref_length" must be explicitly specified when acceleration file ("bodyforce" file) is present.
The solver has no fallback method for calculating the reference length when a time-varying spatially uniform external acceleration field via "bodyforce" file is requested. Please provide a value for "ref_length" keyword in "domain" section explicitly to recover from this error.

### EDM5

The simulation cannot start without a valid "domain" section.
The cfg file must contain a "domain" section. Please define one and assign appropriate values. Please ensure that there are no typographical mistakes and the cfg file has Linux line endings.

### EDM6

The simulations should be either two- or three-dimensional.
The solver does not support one-dimensional simulations. Please set "ndim" to either 2 or 3.

### EDM7

Input for"min_domain" and "max_domain" is inconsistent.
If specified manually, the domain size input for "min_domain" and "max_domain" must span a box, with max > min for all coordinate directions in the simulated dimensions. This warning may point to possible typographical errors in the cfg file.

### EPR13

Failed to compute parallel vector for probe S1. Please specify the parallel vector manually using "probe_tanvec" field.
The solver was not able to compute the parallel vector of a flowrate probe using the probe points. This error may point to an issue within the probe file. Specifying "probe_tanvec" in the cfg will circumvent this error message.

### EPR14

The computed parallel vector for probe S1 is not perpendicular to the specified normal vector. Please specify the parallel vector manually using "probe_tanvec" field.
The parallel vector of a flowrate probe computed by the solver is not perpendicular to the probe normal "probe_nrmvec" specified in the cfg (dot product greater than 1.0e-3).
