Hi,
Where I could find information about "Jass hardening" for Solaris10?
Because, I change the /opt/SUNWjass/Files/etc/syslog.conf file. But yet I don't know if I must restart the jass (and how?) or I must to copy /opt/SUNWjass/Files/etc/syslog.conf to /etc/syslog.conf?

b8 development goes on
The next b8 release (0.5) will be a major one with major changes. Oliver Lillie sent me a basic PHP 5 port of b8, I used his code as the base for b8 0.5. Almost all parts have been completely rewritten, only the math remains untouched.
The most significant changes are:... (0 Replies)

I have Jass Toolkit 4.2 for Solaris 10.
If I run #jass-execute -d secure.driver
and then enable certain services which were disabled by jass, such as ssh,
how do I incorporate those changes to jass so that when i rerun jass-execute secure-driver, it does not complain.
Any suggestions please,... (1 Reply)

After I run Jass , I can bring up the SMC GUI, but it wont let me log in as root. It works without Jass being run. Does anyone know what in Jass disables this. I have tried removing some things from jass like remote-root-login to no avail.
Any hints would be greatly appreciated.

mass(3rheolef) rheolef-6.1 mass(3rheolef)
NAME
mass -- L2 scalar product
SYNOPSIS
form(const space& V, const space& V, "mass");
form(const space& M, const space& V, "mass");
form (const space& V, const space& V, "mass", const domain& gamma);
form_diag(const space& V, "mass");
DESCRIPTION
Assembly the matrix associated to the L2 scalar product of the finite element space V.
/
|
m(u,v) = | u v dx
|
/ Omega
The V space may be either a P0, P1, P2, bubble, P1d and P1d finite element spaces for building a form see form(2).
The use of quadrature formulae is sometime usefull for building diagonal matrix. These approximate matrix are eay to invert. This proce-
dure is available for P0 and P1 approximations.
Notes that when dealing with discontinuous finite element space, i.e. P0 and P1d, the corresponding mass matrix is block diagonal, and the
inv_mass form may be usefull.
When two different space M and V are supplied, assembly the matrix associated to the projection operator from one finite element space M to
space V.
/
|
m(q,v) = | q v dx
|
/ Omega
for all q in M and v in V.
This form is usefull for instance to convert discontinuous gradient components to a continuous approximation. The transpose operator may
also be usefull to performs the opposite operation.
The following $V$ and $M$ space approximation combinations are supported for the mass form: P0-P1, P0-P1d, P1d-P2, P1-P1d and P1-P2.
EXAMPLE
The following piece of code build the mass matrix associated to the P1 approximation:
geo g("square");
space V(g, "P1");
form m(V, V, "mass");
The use of lumped mass form write also:
form_diag md(V, "mass");
The following piece of code build the projection form:
geo g("square");
space V(g, "P1");
space M(g, "P0");
form m(M, V, "mass");
SCALAR PRODUCT ON THE BOUNDARY
Assembly the matrix associated to the L2 scalar product related to a boundary domain of a mesh and a specified polynomial approximation.
These forms are usefull when defining non-homogeneous Neumann or Robin boundary conditions.
Let W be a space of functions defined on Gamma, a subset of the boundary of the whole domain Omega.
/
|
m(u,v) = | u v dx
|
/ Gamma
for all u, v in W. Let V a space of functions defined on Omega and gamma the trace operator from V into W. For all u in W and v in V:
/
|
mb(u,v) = | u gamma(v) dx
|
/ Gamma
For all u and v in V:
/
|
ab(u,v) = | gamma(u) gamma(v) dx
|
/ Gamma
EXAMPLE
The following piece of code build forms for the P1 approximation, assuming that the mesh contains a domain named boundary:
geo omega ("square");
domain gamma = omega.boundary();
space V (omega, "P1");
space W (omega, gamma, "P1");
form m (W, W, "mass");
form mb (W, V, "mass");
form ab (V, V, "mass", gamma);
