### Description When model has been run, has discrete variable connections change, and then get re-run, an error occurs. ### Example ```python The following simple example (with continuous variables) shows...

### Desired capability or behavior. N2 diagrams show Array data. Often this data is very long and when upper/lower bound constraints are in place, usually at a glance one may...

'Solo' a Chain

2

The highlighting of chains is a great feature. I was wondering if this feature could be extended to 'solo' a chain. Essentially re-rendering the graph with only the selected chain...

### Desired capability or behavior. In some cases, derivatives are very close to 0. This can cause relative error checks to fail. It may be worth to adding a parameter...

Auto-Prune Constraints with None as the Upper and Lower Bound

3

### Desired capability or behavior. In my project, many constraints are user settable. This might look like ```python class Comp(om.ExplicitCompoenent): def initialize(self): self.declare('con1_upper', default=None) self.declare('con1_lower', default=None) def setup(self): .... self.add_constraint('con_1',...

### Desired capability or behavior. In my project, some large top level components end up with hundreds of options. In the N2 diagram, when displaying the class options, this can...

### Description The check magnitudes are all 0's for the states with `input_initial=True` ### Example ```python import openmdao.api as om import dymos as dm import matplotlib.pyplot as plt from dymos.examples.oscillator.oscillator_ode...

Feature Suggestion: add_input `require_connection` parameter

1

### Desired capability or behavior. Is there a way a feature could be added that raises an error if a value is unconnected? When a value if left unconnected, it...

### Desired capability or behavior. Would it be possible to switch the headers to black? The white font color blends in to background making it challenging to ready, particularly on...

POEM_96 Implementation: Minimization of Constraint Violation (SciPy Driver Only)

4

### Summary I've created a possible implementation for POEM_96 (https://github.com/OpenMDAO/POEMs/pull/194). I tried to make minimal changes to the overall codebase, so this approach adds a driver level option `minimize_constraint_violation` to...
