NAME
IO_getScalar
SYNOPSIS
IO_getScalar(char*(in) :: name,
real/int/str/log(in) :: value)
DESCRIPTION
This function gets a scalar from a linked list implemented under the hood. In FLASH3 what we mean by scalars are single value variables associated with an entire flash run. These scalars are in contrast to Grid scope variables which need to be stored at each zone of each block in the simulation. Density, pressure and temperature are examples of Grid scope variables while simTime, dt, globalNumBlocks are single quantities associated with the entire run. Scalars of this type can be integers, reals, strings or logical values. An example of a string scalar might be the FLASH3 run comment, name of the logfile or setup line
ARGUMENTS
name: name of scalar value: scalar value
EXAMPLE
USE IO_interface, ONLY : IO_getScalar
real :: dt
call IO_getScalar('dt', dt)
NOTES
Because IO_getScalar is an overloaded function a user calling the routine must USE the interface IO_interface. (Under the hood IO_getScalar under the hood it calls IO_getScalarReal, IO_getPreviousScalarInt, IO_getScalarStr, or IO_getScalarLog and keeps a separate list for each type.)
