WEB input code and execution code
User enters definition of PDE through web interface.
User input is converted to compilable code, pdedef.lang
PDE solution is computed, optional plots generated,
user is presented the solution.

This is just the initial PDE of second order
in three dimensions, in "C", Java, Fortran, Ada

Source code for "C" version, one example
pde23_eqn2.c solver source
nuderiv.c utility source
pde23_eqn2_c.out output
pde23_eqn2_c.dat data for plots
plot3d.java source to generate plots

pde23form.html WEB input
pdedef232.c generated source
pdedef232.h generated source

Commands to compile and run above
gcc -o pde23_eqn2 pde23_eqn2.c pdedef232.c nuderiv.c -lm
pde23_eqn2 > pde23_eqn2_c.out # writes pde23_eqn2_c.dat for plot3d      
javac -cp . plot3d.java
java  -cp . plot3d < pde23_eqn2_c.dat

One screen from java -cp . plot3d < pde23_eqn2_c.dat


Screen from data entry into pde23form.html




Source code for java version, one example
pde23_eqn2.java solver source
nuderiv.java utility source
simeq.java utility source
pde23_eqn2_java.out output
pde23_eqn2_java.dat data for plots
plot3d.java source to generate plots

pde23form.html WEB input
