Constructor.
Takes a reference to a constant mesh object. To set the properties, we input a bitwise OR of the GnuPlotIO::PlottingProperties enumerations, e.g. GnuPlotIO::GRID_ON | GnuPlotIO::PNG_OUTPUT
|

Return/set the precision to use when writing ASCII files.
By default we use numeric_limits<Real>::digits10 + 2, which should be enough to write out to ASCII and get the exact same Real back when reading in.

This method implements writing a mesh with nodal data to a specified file where the nodal data and variable names are provided.
Reimplemented from libMesh::MeshOutput< MeshBase >.
|
virtualinherited |
This method should be overridden by "parallel" output formats for writing nodal data.
Instead of getting a localized copy of the nodal solution vector, it is passed a NumericVector of type=PARALLEL which is in node-major order i.e. (u0,v0,w0, u1,v1,w1, u2,v2,w2, u3,v3,w3, ...) and contains n_nodes*n_vars total entries. Then, it is up to the individual I/O class to extract the required solution values from this vector and write them in parallel.
If not implemented, localizes the parallel vector into a std::vector and calls the other version of this function.
Reimplemented in libMesh::Nemesis_IO.

std::string libMesh::GnuPlotIO::axes_limits |
GNUplot automatically adjusts the x and y-axes of 2D plots to "zoom in" on the data.
You can set this string to force GNUplot to maintain a fixed set of axes. Example: axes_limits = "[0:1] [0:1]" would force x and y to be plotted on the range 0<=x<=1 and 0<=y<=1 regardless of where the data lie.
