Dot indexing is not supported for variables of this type.

Why do I get that error? I am using the AI-mag FEM/ANN Code but when it comes to plotting the outcome, I get this error

We don't know how your structure "var_inp" is built up - thus we cannot help without code that reproduces the error.

@Torsten does this help now?

% Initialize the variable structure

var_inp = {};

% Add variables based on the model type

if any(strcmp(model_type, {'ht', 'mf'}))

% Inner radius

var_inp{end+1} = struct('name', 'rin', 'var_trf', 'none', 'var_norm', 'none', 'min', 0.75, 'max', 0.75); % Fixed value

% Number of turns

var_inp{end+1} = struct('name', 'N', 'var_trf', 'none', 'var_norm', 'none', 'min', 35, 'max', 35); % Fixed value

% Wire width

var_inp{end+1} = struct('name', 'wire_width', 'var_trf', 'none', 'var_norm', 'none', 'min', 4, 'max', 4); % Fixed value

% Distance between turns

var_inp{end+1} = struct('name', 'turn_distance', 'var_trf', 'none', 'var_norm', 'none', 'min', 4, 'max', 4); % Fixed value

% Air gap length (variable)

var_inp{end+1} = struct('name', 'airgap', 'var_trf', 'none', 'var_norm', 'min_max', 'min', 50, 'max', 250);

You don't have a substructure with name "var_norm.min". All structure elements are at the same (first) level.

var_inp{1} = struct('name', 'rin', 'var_trf', 'none', 'var_norm', 'none', 'min', 0.75, 'max', 0.75); % Fixed value
var_inp{end}

ans = struct with fields:
        name: 'rin'
     var_trf: 'none'
    var_norm: 'none'
         min: 0.7500
         max: 0.7500

var_inp{end}.var_norm

ans = 'none'

var_inp{end}.min

ans = 0.7500

var_inp{end}.var_norm.min
