No

Explanation

101

An analysis was terminated, due to insufficient memory available.

110

An analysis was terminated, because the network hydraulic equations could not be solved. Check for portions of the network not having any physical links back to a tank or reservoir, or for unreasonable values regarding network input data.

200

One or more errors were detected in the input data. The nature of the error will be described by the 200-series error messages listed below.

201

There is a syntax error in a line of the input file, created from the network data. This is most likely to have occurred in the *.INP text file, created by the Wadiso program, and stored as WadZEPA.INP. on the ...\Windows\Temp\Wadiso5 directory. Call GLS Consulting if this happens.

202

An illegal numeric value was assigned to a property.

203

An object refers to an undefined node.

204

An object refers to an undefined link.

205

An object refers to an undefined time pattern.

206

An object refers to an undefined curve.

207

An attempt is made to control a check valve. Once a pipe is assigned as a Check Valve, its status cannot be changed by either time-, clocktime-, simple- or rule-based controls.

208

Reference was made to an undefined node. This could occur in a control statement, for example.

209

An illegal value was assigned to a node property.

210

Reference was made to an undefined link. This could occur in a control statement, for example.

211

An illegal value was assigned to a link property.

212

A source tracing analysis refers to an undefined trace node.

213

An analysis option/setting has an illegal value (an example would be a negative time step value).

214

There are too many characters in a line read from an input file. The lines in the *.INP file are limited to 255 characters (See also 201 above).

215

Two or more nodes or links share the same ID number.

216

Energy data were supplied for an undefined pump.

217

Invalid energy data were supplied for a pump.

219

A valve is illegally connected to a reservoir or tank. A PRV, PSV or FCV cannot be directly connected to a reservoir or tank. Use a length of pipe to separate the two.

220

A valve is illegally connected to another valve. PRVs cannot share the same downstream node, or be linked in series, PSVs cannot share the same upstream node, or be linked in series, and a PSV cannot be directly connected to the downstream node of a PRV.

221

A rule-based control contains a misplaced clause.

223

There are not enough nodes in the network to analyse. A valid network must contain at least one tank/reservoir node and one ordinary node.

224

There is not at least one tank or reservoir in the network.

225

Invalid lower/upper levels were specified for a tank (e.g., the lower lever is higher than the upper level).

226

No pump curve was supplied for a pump. A pump must be assigned a curve ID Number, or 1, 2 or 3 pairs of Flow/Head data must be provided.

227

A pump has an invalid pump curve. A valid pump curve must have decreasing head with increasing flow.

230

A curve has non-increasing X-values.

233

A node is not connected to any links.

302

The system cannot open the temporary input file.

303

The system cannot open the status report file. See Error 302.

304

The system cannot open the binary output file. See Error 302.

308

Could not save results to file. This can occur if the disk becomes full.

309

Could not write results to report file. This can occur if the disk becomes full.
